OCZ Value VX Thread

[Mondo1287]

I'd like to know what others have their Value VX running at and with what settings. Specifically part # OCZ4001024WV3DC-K

 

I'm currently running at [email protected] Its stable for the most part, but prime95 torture test crashes the machine within 45 minutes usually at any speed above 215mhz.

I have the PC3200 VX, running on mostly auto settings, expect the important and not so confusing ones that make up the first chunck of memory settings. I have managed to get 262mhz at 1.5-2-2 timings. Note that I am only using 1 stick because the other died, and it takes 3.7v to get it stable at 262mhz. 257mhz is stable at 3.5v though, and 258mhz only gets 2 errors a pass at 3.5v.

 

I'll check my other settings, but some of your settings seem a bit too tight to run very well.

 

(note that the other stick died from unrelated reasons, I still had it running at 2.6v when it died).

What's the highest FSB this ram can do at cas2 1t?

[Tom Brohanks]

My max stable has been 215 with 3.1v at 10-2-2-2 1t

[SaFrOuT]

search the forum since there was a huge thread talking about this mem with a lot of results including mine

 

and beside the setting in my sig my ram can lately do DDR400 @ 2-2-2-8 @ 2.5Vdimm only

[spiroh]

Well guys, it looks like my memory cant even hit 236 without having an error. I tried every voltage up to 3.6 and still nothing. I had it set at Cas2-2-2-6 1t.

[SaFrOuT]

do u have active cooling on them and what si the rest of ur timings

 

i suggets keeping the rest to auto while testing

[spiroh]

I got this from sharp on this forum:

 

Hello,

 

Set the memory voltage to 2.8v and try 2-2-2-5

u shoudl change those to Auto and see

and change this to 8 or 7 since AMd65 likes them more than 5

and which bios r u sing and in which dimms have u installed them ?

BIOS 623-3 (official dfi) orange slots.

[SaFrOuT]

man u should read the stickies which recomand that for our Winbond based ram to use bios with extension -2 or maybe -1 but -3 is optimized for TCCD/TCC5 based mem

[Mondo1287]

Well I switched to the 623-2 bios, and I also read that the yellow slots are better for high voltage memory? Can anyone confirm that? Anyway I also switched to the yellow slots at the same time I flashed the new bios. I'm now 12hours prime95 stable at 230mhz at 2-2-2-6 and 3.4v with most of everything else on auto so either the yellow slots or the 623-2 bios helped out quite a bit. I think it was both though, I'm pretty sure that with the 623-3 bios the yellow slots wouldn't work for me. I'm going to see how high I can get on 3.4v, I'll let you guys know.
