Hi All,
I'd like to thank all on these forums first for posting really helpfull info that's enabled me to start properly o/c'ing my system rather than using the uGuru software (i.e using the BIOS). I have found the variation in terminology for things a little confusing at times but I think I'm there.
System is:
A64 Venice 3200+
2 x 1Gb Buffalo non matched PC3200 3-3-3-8 @ DDR400 (one stick with hyundai other with melco chips)
Abit AN8 non-SLI fatal1ty
Zalman 90mm copper 'flower' HSF
350W power supply, can't remember the manufacturer but it's not generic
HIS X800XL
1 x IDE drive
1 x SATA drive
2 x Optical drives
2 x 80mm fans at the front
1 x 80mm fan at the rear
Admittedly I've skimped on the RAM but had to and at the time I didn't understand the point of getting > 3200 DDR for the system. I've been following advice and slowly increasing things to get higher and higher. At first I just concentrated on the HTT frequency but I seem to have reached it's limit a lot faster than other people even after tweaking voltages.
The link shows what I've been trying:
o/c matrix
* = very warm room
** = cool room
*** = warm room
Column 1-3 is me trying to find out the max HTT without taxing the CPU or memory (I think). I've read that people can get up to 300 easily which has me slightly disappointed as I could never get settings in column 3 to run Prime95 for very long at all. I've not put in the volts as I tried many different combinations.
As I thought 240 was my HTT limit I tried uping the CPU. Due to my RAM not being super quick I'm never going to bother trying to get the RAM going faster than 220, the fastest preset uGuru had, which my system could happily run on. So column 4-7 is me winding up the CPU slowly which strangely enabled me to get the HTT upto 250 with faster RAM and CPU timings????
Feeling flush with my success in getting the HTT to 250 I'd thought I'd try to get the CPU to 2500. I've included in the highest voltages I'd tried for the CPU and HT.
By this time for testing I'd start Prime95 with the first test (small FFT), then second (In place large FFT) and finally the third (blend) before thinking the settings were stable. If it failed on test 1 I'd up the CPU and poss HT voltage until it was ok. The 2nd test I'd up the CPU, HT and possibly DDR volts if needed, the third test, it would mainly need more DDR voltage.
I'm now unable to get the settings in column 7 working past the second prime95 test and I'm in, for me, risky territory. I really want the settings in 7 to work and think they could but I don't want to damage my hardware, so:
Can I up the CPU volts some more safely, say to 1.6+?
Are the temps in column 7 too hot?
What is PWM and vvt?
The volts quoted are the settings in the BIOS; Speedfan, cpu-z and uGuru
all reported slightly higher volts when in windows (0.03 to 0.1) is this
normal?
FYI I researched my RAM and their documentation does rate the DIMMS to
2.8v if this would help.
Once again thanks for the n00b guides posted with out which I'd not have
reached this far!!
Cheers
