Ok, well, im checking out my system with some Twionmos/Winbond pc3200 ch-5 512mb stuff. I just started it up at 12x180 6332 which my hyperX would only do on my board (never got it past 180). Now it running stable (2 passes memtest 0 errors) and (1hr prime no errors). All is running at default voltages.

Question: What timings does this memory like and how high should i look to go without a different northbridge cool?
Do i need to up vdimm or do these chips run fine at default. Any info on the chips would be great. Thanx

Give it 200mhz at least. I have 2x512 of the BH-5 chips running @ 200 2-2-2-5. They'll go higher but I suspect my mb (NF7-S v2.0) of stability issues @ higher fsb.

Now. I upped it to 12x185 and got no errors 2 passes memtest but error 1min into prime. Upped vcore to 1.7 and running prime stable 30min. 40c-41c. temps idle 35-36c

Link to voltages and all. What should i do from here volteages ok under load?

PS: Confirmed HYPERX sux on my board. I mean hell, with no effort im at 185fsb with twinmos unlike my 180wall with hyperx

2-2-2-6, Tras of 5 has been known to cause Hard drive corruptions. You won't notice the difference anyways.

OK. ran default at 9x200 and ran mem test 2 passes no erorrs. Took 2x longer than usuall and read 442mb/s. Rebooted after test and went into bios and changed to 10x200 and no go. default vdimm and vcore 1.7. Got c1 error and beeping. Whats going on?
changed timinigs from 6332 to 6222. No go. Had to use insert both times to get into bios. BTW at 200 when i hold insert to boot it read 100fsb? Why but in bios 200mhz

Try to keep TRCD (RAS to CAS Delay) to 3...say run at 6-3-2-2 and raise vdimm to 2.77?

tries 6332 for 9x200 and 10x200. Can i up the vdimm on this chip. I thought the ch-5 was not good with that

ok did 8x200 fsb 2 passes in memtest at default voltages. NO GO errors all over mem test.
upped vdimm to 2.77 (2.8 in cpuid) and ran 8x200 at 6322 for 2 passes. No errors. Was the vdimm my problem?
Am i fine now. Dont want anything to blow

2.77v in your BIOS is good. In fact you can still up it to 2.9v without worries :D

also marvie. you heard that the ch-5 is delicate to voltage right?

I dont have nb cool so i dont know how much higher ill get. Temps under prime are 38-39 under load

Ok well ran 11x200 with the Twinmos ch-5 for 16 hours no errors and no errors in memtest default settings 2 passes. Decided to do all tests today (not default) and got an error on test 3 and let it continue . No more errors. Restarted it twice and ran it though 2-3 passes both times and the error never returned. Whats going on?

Also i still dont know why i need my voltage at 2.77 for 200fsb at 6322.
