Hi, I started some 6 weeks ago crunching SETI MB 7.0 & 7.03 and AP 7.04 WU's.
Running stock app. BOINC 7.2.42 on an I7-2600 and 2 ATI 5870 GPU's.



I hope my links are correct?!
Correct me if I'm wrong, please.

I just started to crunch SETI again with 1 computer and noticed some
server problems, but I get enough work for now MB 7.0 and 7.03 also AP 7 WU's.
Seeing a lot off mega crunchers b.t.w.

When using high-end GPU's make sure your PSU has enough separate +12V -18 to 25Amp connectors.
Best to supply each GPU with it's own +12V rail, especially twin GPU's.
They 'll need almost 30Amp's when used at 100%.

I now us 2 AMD/ATI HD5870* GPÚ's, each has a separate +12V 22Amp 8 pin PSU connector.
The Mobo has it's own connector, + 3.3V; + 5V ad + 12V.
* Each GPU can draw 180Watt at 100% load.

I use a Kill A Watt (K)Watt meter, doing 4 Einstein BRPS WU's, 2 per GPU and all
8 'cores' off the I7-2600 are used at 100%, the PC draws 465 Watt, according to the Watt meter.
The HDD's also have there own power supply connector, +5V and + 12V.

Some "overhead" is more off a safety measure. 25% to 50% is sufficient.
Most PSU's have about 98% efficiency and hardly produce any extra heat.
I use a 1KWatt modular PSU. It has 6 +12V connectors, 4 are 24 Amp\s.

Well just take your time browsing these forums, maybe take a look at the

Considering the amount off data SETI has to handle, I don't even start
to explain the different SERVER job's and the sending and receiving off WU's.

There certainly will be someone far better at explaining the in 's and out 's
off the whole SERVER CIRCUS ;^)

Just take your time . . .

Speaking about "cloud"[s] and persistent e-mails how important my 'data' could be, storage in a secure cloud, was the most cheapest way keeping my precious data
I end up making my own 'cloud' in a USB 2.0/3.0 HDD's kept somewhere else in my house.

Aren't they not yet fixed. ?!
Can the splitters overflow? Is this an AstroPulse issue or also MB work
And I run several other projects . Getting work isn't an issue ;^)) .

I'm working on a second computer, then a third . which has to be more power ful as the PC I now use so a 20core XENON. and 4 High End GPU's f.i.that will solve that %^) . . .it can be even become an addiction, a way of live .(I"m also an Oxycontin/HydroMorfone (Palladon 1 -2 and 4mG tablets user, these are powerfull narcotics but great pain killers).

Haswell is the codename for a processor microarchitecture developed by Intel as the successor to the Ivy Bridge architecture.[1] It uses a 22 nm process.[2] Intel officially announced CPUs with this microarchitecture on June 4, 2013 at Computex Taipei 2013.[3] With Haswell, Intel introduced a low-power processor designed for convertible or "hybrid" Ultrabooks, having the Y suffix. Intel demonstrated a working Haswell chip at the 2011 Intel Developer Forum.[4]
Haswell CPUs are used in conjunction with the Intel 8 Series chipsets and Intel 9 Series chipsets.

The Haswell architecture is specifically designed[5] to optimize the power savings and performance benefits from the move to FinFET (non-planar, "3D") transistors on the improved 22 nm process node.[6]
Haswell has been launched in three major forms:[7]
Desktop version (LGA 1150 socket): Haswell-DT
Mobile/Laptop version (PGA socket): Haswell-MB
BGA version:
47 W and 57 W TDP classes: Haswell-H (For "All-in-one" systems, Mini-ITX form factor motherboards, and other small footprint formats.)
13.5 W and 15 W TDP classes (MCP): Haswell-ULT (For Intel's UltraBook platform.)
10 W TDP class (SoC): Haswell-ULX (For tablets and certain UltraBook-class implementations.)
ULT = Ultra Low TDP; ULX = Ultra Low eXtreme TDP
Only certain quad-core variants and BGA R-series SKUs receive GT3e (Intel Iris Pro 5200) integrated graphics. All other models have GT3 (Intel HD 5000 or Intel Iris 5100), GT2 (Intel HD 4200, 4400, 4600, P4600 or P4700) or GT1 (Intel HD Graphics) integrated graphics.[8] See also Intel HD and Iris Graphics for more details.
Due to the low power requirements of tablet and UltraBook platforms, Haswell-ULT and Haswell-ULX are only available in dual-core configurations. All other versions come as dual- or quad-core variants.
Compared to Ivy Bridge:
Approximately 8% better vector processing performance.[9]
Up to 6% faster single-threaded performance.
6% faster multi-threaded performance.
Desktop variants of Haswell draw between 8% and 23% more power under load than Ivy Bridge.[9][10][11]
A 6% increase in sequential CPU performance (eight execution ports per core versus six).[9]
Up to 20% performance increase over the integrated HD4000 GPU (Haswell HD4600 vs Ivy Bridge's built-in Intel HD4000).[9]
Total performance improvement on average is about 3%.[9]
Around 15 °C hotter than Ivy Bridge, while clock frequencies of 4.6 GHz are achievable.[12][13][14][15][16][17]
See also: Intel HD Graphics
Features carried over from Ivy Bridge[edit]
22 nm manufacturing process
3D tri-gate transistors
Micro-operation cache capable of storing 1.5 K micro-operations (approximately 6 KB in size)[18]
14- to 19-stage instruction pipeline, depending on the micro-operation cache hit or miss (the same approach as used in predecessor CPUs, Sandy Bridge and Ivy Bridge)[18]
Mainstream variants are up to quad-core[19]
Native support for dual-channel DDR3 memory,[20] with up to 32 GB of RAM on LGA 1150 variants
64 KB (32 KB Instruction + 32 KB Data) L1 cache and 256 KB L2 cache per core[21]
A total of 16 PCI Express 3.0 lanes
New features[edit]
Wider core: fourth ALU, third AGU, second branch prediction unit, deeper buffers, higher cache bandwidth, improved front-end and memory controller
New instructions[22] (HNI, includes Advanced Vector Extensions 2(AVX2), gather, BMI1, BMI2, ABM and FMA3 support).[23]
The instruction decode queue, which holds instructions after they have been decoded, is no longer statically partitioned between the two threads that each core can service.[18]
New sockets and chipsets:
LGA 1150 for desktops, and rPGA947 and BGA1364 for the mobile market.[24]
Z97 (performance) and H97 (mainstream) chipsets for the Haswell Refresh and Broadwell, in Q2 2014.[25]
LGA 2011-v3 with X99 chipset for the enthusiast-class desktop platform Haswell-E.[26]
Intel Transactional Synchronization Extensions (TSX) for the Haswell-EX variant. In August 2014 Intel announced that a bug exists in the TSX implementation on the current steppings of Haswell, Haswell-E, Haswell-EP and early Broadwell CPUs, which resulted in disabling the TSX feature on affected CPUs via a microcode update.[27][28][29][30]
Hardware graphics support for Direct3D 11.1 and OpenGL 4.3.[31][32][33]
DDR4 for the enterprise/server variant (Haswell-EX and E5v3 SKUs)[34] and for the Enthusiast-Class Desktop Platform Haswell-E[35]
Variable Base clock (BClk)[36] like LGA 2011.[37]
Four versions of the integrated GPU: GT1, GT2, GT3 and GT3e, where GT3 version has 40 execution units (EUs). Haswell's predecessor, Ivy Bridge, has a maximum of 16 EUs. GT3e version with 40 EUs and on-package 128 MB of embedded DRAM (eDRAM), called Crystalwell, is available only in mobile H-SKUs and desktop (BGA-only) R-SKUs. Effectively, this eDRAM is a Level 4 cache; it is shared dynamically between the on-die GPU and CPU, and serving as a victim cache to the CPU's Level 3 cache.[38][39][40][41][42]
Optional support for Thunderbolt technology and Thunderbolt 2.0[43][44]
Fully integrated voltage regulator (FIVR), thereby moving some of the components from motherboard onto the CPU.[45][46][47]
New advanced power-saving system; due to Haswell's new low-power C6 and C7 sleep states, not all power supply units (PSUs) are suitable for computers with Haswell CPUs.[48][49]
37, 47, 57 W thermal design power (TDP) mobile processors.[19]
35, 45, 65, 84, 95 and 130–140 W (high-end, Haswell-E) TDP desktop processors.[19]
15 W TDP processors for the Ultrabook platform (multi-chip package like Westmere)[50] leading to reduced heat, which results in thinner as well as lighter Ultrabooks, but the performance level is lower than the 17 W version.[51]
Shrink of the Platform Controller Hub (PCH), from 65 nm to 32 nm.[52]
Haswell-EP models with more than 10 cores support cluster on die (COD) operation mode, allowing CPU's multiple columns of cores and last level cache (LLC) slices to be logically divided into what is presented as two non-uniform memory access (NUMA) CPUs to the operating system. By keeping data and instructions local to the "partition" of CPU which is processing them, thus decreasing the LLC access latency, COD brings performance improvements to NUMA-aware operating systems and applications.[53]
Translation lookaside buffer sizes[54][55]
Cache Page Size
Name Level 4 KB 2 MB 1 GB
DTLB 1st 64 32 4
ITLB 1st 128 8 / logical core none
STLB 2nd 512 none
Expected server processors features[edit]
Release by the end of 2014.[citation needed]
Haswell-EP variant, with up to 18 cores and marketed as Xeon E5 2600 v3 series.[56]
Haswell-EX variant, with 18–20 cores[citation needed] and functioning TSX.[29]
A new cache design.
Up to 35 MB total unified cache (Last Level Cache (LLC)) for Haswell-EP[57] and up to 40 MB for Haswell-EX.
LGA 2011-v3 socket replaces LGA 2011 for the Haswell EP; the new socket has the same number of pins, but it is keyed differently due to electrical incompatibility.[58][59][60]
The already launched Xeon E3 v3 Haswells will get a refresh in spring 2014,[61] together with a refreshed Intel C220 series PCH chipset.[62]
TDP up to 160 W for Haswell-EP.[63]
Haswell Refresh[edit]
According to Intel roadmaps, Broadwell will be released in first half of 2015, thus around the middle of 2014 Intel released a refresh of Haswell, simply titled Haswell Refresh. When compared to the original Haswell CPUs lineup, Haswell Refresh CPUs offer a modest increase in clock frequencies.[64] Haswell Refresh CPUs are supported by Intel's new 9 Series chipsets (Z97 and H97, codenamed Wildcat Point), while motherboards with 8 Series chipsets (codenamed Lynx Point) usually require a BIOS update to support Haswell Refresh CPUs.[65]
The CPUs codenamed Devil's Canyon, covering the i5 and i7 K-series stock keeping units (SKUs), employ a new and improved thermal interface material (TIM) called next-generation polymer thermal interface material (NGPTIM). This improved TIM reduces the CPU's operating temperatures and improves the overclocking potential, as something that had been problematic since the introduction of Ivy Bridge.[66] Other changes for the Devil's Canyon CPUs include a TDP increase to 88 W, additional decoupling capacitors to help smooth out the outputs from the fully integrated voltage regulator (FIVR), and support for the VT-d that was previously limited to non-K-series SKUs.[67] TSX was another feature brought over from the non-K-series SKUs, until August 2014 when a microcode update disabled TSX due to a bug that was discovered in its implementation.[29][30]
Intel also released the Pentium Anniversary Edition (Pentium G3258), an unlocked and highly overclockable processor that marks 20 years of "Pentium" as a brand.

I"d rather use 2 high end video cards, the bigger the better.
I now use AMD/ATI 2 HD 5870 GPU's. They are great using OpenCL speed up 500 times faster are realistick, Collatz C ; MilkyWay; GPUGrid had very efficient use and thus 200 - 800 times faster.
Both video cards and CPU maxed out, the rig uses 575 Watt. It has a 1000Watt PSU.
In that case the whole rig gets too hot and a big fan 40cm diameter 9600 rpm max. is used to get rid off the heat and for now I sometimes use it.

Doesn 't make the GPU's running at 99% load, a lot off noise?
Reminds me doing MilkyWay, GPU's @ 99% making sound like an jet, taking off.

Something completely different, still running BOINC 7.2.42 (stock),
using an I7-2600 and 2 AMD/ATI HD5870 GPU's.
[In Einstein@home I run 2 WU's on each GPU].
And I already experience heat problems on the CPU. which has a stock-cooler.
CPU on 90% --> temp >/= 97C, GPU 's 58 and 64C.[2 E@Home WU's on each GPU.]
[This rig draws 465 Watt].
A better cooler for the CPU is necessary when running optimized app. 's in fact
100% use sometimes shut's the PC off, thermal shutdown @ 110C !
PSU has enough capacity 1KWatt.

Posted 23 Aug 2014 by Profile Fred J. Verster
I started yesterday, since 18 months off absense and installed the latest BOINC
64Bit on WIN 7, 64Bit.
PC: I7-2600 (HT=ON)16GB DDR 3 1600MHz. DRAM and 2x HD5870 GPU's.
PSU= 1000Watt.
I'd set the CPU to a higher TURBO Freq. 3.9 i.s.o/ 3.8GHz. and also aupped some
offset CPU voltages. This inmediatly cased not only overheat problems but real
instabillity! And lock-ups, BLUE-SCREENS and crashes.
Loading the B.I.O.S. settings for this particular CPU, caused the system to respond normally. CPU, with sock-cooling,[HT=ON] caused inmediat overheating problems, choosing 70% CPU load and a auxilliary fan took care offt that.
By the way, CoreTemp and INTEL DeskTopUtillities reported 101C for all 4 CPU's
[HT=ON], but the temp switched as fast as the core-load and caused no added

The HD 5870 GPU's are running at ~75% off their crunching capacity did run smooth, the whole system uses 500Watt/hour and is very stable also use it for
browsing and forum posts, e-mail and other minor tasks, causing no problems
with BOINC running 'all the time' setting. I use 1 monitor on each GPU and enough 'head-room' is available the use these quite normally, although no smooth
graphics-display f.i web-cam or videos.

It took less then 8 hours to get me to post on these forums, enough work was done and validated.

Nice to see both S@H and AstroPulse science-app's in BOINC manager behave
beautiful without any tuning.
Both HD5870 GPU's run at 75% off their maximum capacity.
The CPU, I7-2600 with stock cooler get too hot with HT on, so a setting off
70% and an auxillairy fan, is necessary.
Tipp off the hat for implementing the OpenCL app's in BOINC manager!
And ofcoarse the testing, tuning and getting the OpenCL app's to work in BOINC.

And no problem to use the computer for 'other' purposes as well.
