A8N-SLI Primium

AMD Athlon 64 4000+ San Dieago Clocked @ 2.92Ghz

CPU Frequency 290
CPU Voltage (Vcore) 1.475v
Hyper Thransport Frequency X3
CPU Multi X10

GeIL 2GB (2x1GB) DDR PC3200 CAS3 Divided 266Mhz
DDR Voltage 2.80V

2 Point OF View 7800GT's clocked At Core Clock 451Mhz Memory Clock 1100Ghz

Creative Fatlity X-Fi Sound Card 64 X-Ram


3DMark05 Score = 12,062

This is the first ever attempt at Overclocking for me. Although this may not be this PC's limit it has all been done on Standard cooling...it seems to run stable through out the 3Dmark05 tests and whilst playing F.E.A.R!

I'm open to all sorts of comments, good or bad...so please feel free,

Thanks
 
Within the first 10 seconds of the Blend torture test in Prime95 this came up:

FATEL ERROR Rounding was 0.4999998361, Expected Less than 0.4

Hardware Failure detected,

1 Error, 0 Warnings

Tortoure Test Halted

The systems runs games etc, and 3Dmark05 so i don't understand why this is happening, i used to get pyhsical memory dumps with the blue screen of death, this doesn't happen now....Please help...i don't know enough about RAM.

Thanks
 
Is this a normal problem??? Because all i've done is put a divider 266MHz and changed the DDR Voltage to 2.80V to help with the CPU overclock...

I tested the RAM on that memory tester programe before the overclock, it ran for 6 hours with no errors....so could this be hardware (RAM) related???
 
New Overclock

AMD Athlon 64 4000+ San Dieago Clocked @ 2.7Ghz Standard Cooling
(Now stable for 10+ hours, this is before I stopped the tests this morning)
CPU Frequency 225
CPU Multiplier X12
DDR Voltage 2.60V - 2.70V (seems faster with higher voltage though)
CPU Voltage (Vcore) 1.450V (more stable than standard 1.400V)
Hyper Transport Frequency Set to X4 (FSB 900)

GEIL 2GB RAM PC3200 at 2-3-3-6 with ½ Divider running @ 200Mhz

My first attempt as I’m sure a lot of you know kept failing Prime95 within a matter of seconds…a lot of you gave advise and a few good tips an ideas although none worked at keeping the system stable @ 2.92Ghz on standard cooling. Regardless of RAM timings, CPU voltage or DDR Voltage all attempts failed…I ran memory tests out of windows before overclocking for at least 6 hours, no errors were found. I can safely say that with only a few days of hands on experience I can tell you that to truly have a stable system you have to have stable RAM, Which the GEIL 2GB setup isn’t. I’ve read reviews on the net saying there is no way of getting these modules past 214Mhz on any latency settings. Even with a divider I find it hard to find a stable Overclock that allows Prime95 to run for more than 5 minutes without a fatal error. The highest Overclock with this set of RAM modules is with a 2/3 Divider running @ 266Mhz with a latency setting of 3-4-4-8…but I wanted a lower latency there for the only stable setting was with ½ Divider running @ 200Mhz with latency’s of 2-3-3-6.

I hope the above is not all gobbly gup, and that it all actually means something?? Its my first attempt at getting a stable system and I hope what I’ve wrote is to point an more so correct in theory.

Thanks guys for any help…future overclocks will be attempted, keeping you posted I shall.
