Hello all
Just got done building a new machine its an Athlon64 3500 on a gigabteK8nsultra-939 board with 2 gig Pc3200 HyperXfrom Kingston with a radion 9800pro Vid card.what i cant figure is that i have 2 XP one 3200 and a 2600 boxes one with 512 ram other with 1 gig but my new machine is only half hour faster then my standard XP machines.Is there anything i can do to get windows hopping a little bit more?

Matt,
An XP64 running 32 bit code is only slightly faster than a standard XP (for equivalent clock speeds). You're not going to get much more from running a 32 bit application and 32 bit OS on a 64bit machine.

Disable nay processes you don't need.

Make sure you don't leave things like messenge running.

Turn off disk indexing ...

There are more generic hints in the FAQ ...

I think what he means is the following :

His two AthlonXP's (2600+ and 3200+) are only 30 Minutes slower than his new Athlon64 3500+

Looking at his Systems, the times from the AthlonXP 2600+ and the AthlonXP 3200+ are almost identical; a definite anomaly there.

Last 5 normal WU's average
--------------------------

AthlonXP 2600+ : 2h45m
AthlonXP 3200+ : 2h50m
Athlon64 3500+ : 2h15m

As comparison, my AthlonXP 3000+ (Win2000 SP4) comes in at 2h40m using the default Berkeley SETI Win32 Client.

So your AthlonXP 2600+ is definitely very! fast, while the AthlonXP 3200+ is far too slow.
Might be background Tasks, might be RAM Timings or a slow Chipset used. (AthlonXP's rise or fall with RAM bandwidth and Chipset performance)

My Athlon 3700+ (So754, slow PC333 DDR-SDRAM) does a WU in approx. 1h52m, based on that your Athlon64 3500+ should be doing something around 2h or less.

There is a possibility that your Athlon64 System has Cool&Quiet Enabled, which is known to cause Trouble when using Idle Priority Tasks (like BOINC/SETI). In that case, the CPU might not clock back up-to-speed despite 100% CPU usage, resulting in significant loss of performance. Use a freeware Utility like CPU-Z or AMD's CPU Dashboard Demo to display CPU Clock speed in realtime.

PS.
Your Systems performance can be boosted significantly using Tetsuji's optimized V4.11 SETI Clients, found here :

Ty Falconfly Major speed boost for my Athlon64 the 4.11 drivers screem got a 50% increase with them.The XP2600 is on an Asus board and the 3200 in and Emachine that my son won in a raffle gona replace it MoBo with Asus as soon as the wife cools over my new machine if ya know what i mean.
