XP1700 Clocking

[Jonny M]

Currently running this TbredB chip at 180fsb and 12 multiplier (2174Mhz reported in CPU-Z).

Core voltage is at 1.55v, Ram voltage at 2.7v. Going any further than this seems to cause problems with Windows rebooting just as it loads / kernel errors. Any suggestions on where to go from here? Will adding more volts keep things stable? Temps are good (45 degrees under load).

System consists of:

Abit NF7-S v2.0
AMD AthlonXP 1700+ (TbredB, the good ones, can't remember the exact code JIUHB or something?)
2x 512Mb TwinMOS PC3200 (Winbond chips).

Thanks

Forgot to add, Ram timings are 8 3 3 2. Might up the CAS to 2.5 if anyone thinks it will make a difference?

yes, you can test what the bottleneck is by decreasing multiplier and upping the fsb, or vice versa, but i'd guess it's the cpu, to which increasing the voltage should do the trick.

What's a safe level to go to? It runs default at 1.5, so anything up to 1.7 I'd guess should be fine, since the other TbredB were 1.7 default.

1.85V but the higher the voltage the hotter it will get.

you have pc3200 ram so why not try running a 10x200fsb with say 1.7v vcore i had a 1700xp dut3c(1.6v standard the dlt3c is 1.5v standard) and it would run easily at 10.5x206fsb at 1.7v make sure your cpu temps are ok before trying though as BUFF has stated the more volts the hotter it gets

Get the latest BIOS for NF7-S (v2.0) as the older ones dont like 9.5 and 10 multiplers. Then put the timings to 11-3-3-2.0 (11 is more stable, and better performance.) I assume you are running dual channel too?

1.85v is really the ulimate maxium voltage. Just go until you dont see a beneficial performance gain (100mhz-ish)

Right, currently running at 200fsb, 10x multi, 11 3 3 2. 1.6v core.

Getting a general protection fault in UT2004 demo. Is this likely to be a Ram related problem? Ill loop Memtest a bit tomorrow.

Temps are fine btw.

Go to 1.7v, if stable then go to 11x multi
