To enhance ram stability a little more power to the sticks would come handy. Is there a bios for K8N Sli Platinum around featuring MORE than 2,85V for ram AND 200:150 divider?

Thanks BK! Unfortunately those feature 200:150 OR more than 2.85VDimm. I need both features in one bios.

The 5.xx BIOS's for the Diamond are suppose to have 3.1v.

No one has proved that it ever worked.(i.e putting a multimeter to it), but most people saw no stability increase and therefore it is commonly believed that it never worked.

I have a few 5.xx BIOS modded but I don't post them since they are for Diamond users only.  Perhaps we could PM.  :hypocrite:

Diamond bios 5.0b works and 150mhz divider as well as high vdimm available. Although the extra vdimm didn't help my sticks. They're not doing the 242mhz (DDR 484) although 3-4-4-8. I had to reduce htt to now 315mhz :crying: . A pitty because cpu is now only at 2835mhz although it could do more than 2900mhz, only the sticks show errors. Unfortunately I can't do anything about it as no other mem divider works. Even 100 divider stops working when reaching 300mhz htt preventing the sytem to even post.

like aicjofs said, i really doubt that the mobo is actually capable of delivering the 3.1V, so i'm afraid that is just a visual feature in BIOS and does nothing more. remember, on MS-7100 mobos the memory voltage is supplied from the 3.3V rail and with the needed round down due to stabilizing the value cannot get to 3.1V. this is especially since the mobo was never designed for 3.1V. so i can't believe you can get to 3.1V without a hard mod.

really 3.1v or not. I doubt more vdimm would help me, I don't think the C2 would do more than DDR 472. The problem is the divder and no way out.

what's the exact memory model that you have? the Corsair has a lot of C2 parts. the 3200C2 alone has like 5 or 6 revisions too, with different memory chips. find out the memory chips that you have and then you'll know if voltage actually helps or not.

This would take a lot of research as I only know they're CMX1024-3200C2 and Corsair doesn't document when which chips were used. And I don't want to take the heatspreader off and look for the chips. After all it wouldn't even help me if I knew. Whether my board doesn't do more than 2.85vdimm or more wouldn't help I can't do anything about it. If they would need more vdimm and K8N couldn't give them, I'd have to buy a new mobo what I wouldn't do at all. Would be a hell of a waste of money for approx 70-80mhz cpu clock  :bonk:

Only thing helpful would be more dividers but no chance because it's the optys fault.

well you can see their revision, which should be written over memory sticks. then google it to findout what chips are inside. you can check here as well:

newest revision usually do their potential at 2.8-2.9V, anythink over it will bring nothing more.

As I said it wouldn't help me if I knew they'd work better with more vdimm. Setting 3.1v in mod bios doesn't help. That's why I had to buy another board that's supporting 3.0v what would be crazy. My diamond plus would do but I can't use it as no 150mhz divider.... So it wouldn't help me to know what ram I got that's what I'm trying to say. Right now I have no option at all but changing to another opteron what I wouldn't do as I already tested two and both were crap... :wall:

well you can try the memory from diamond on the diamond plus board and to check what can it do with more vcore.

I could do but if I find out it'll work better with more vdimm I'd have nothing won. As I have no board that can give a lot of vdimm and 150mhz divider I could do nothing with the knowledge they'd do more. I don't want just know how much my ram can do, I want more clockspeed to my opty.
If they'd do more or not won't help me out.

yes, but will bring the light and will known the answer and stop bother it :-))

Yep, maybe I'll try although it'll just make me enlighted but still having too slow opty...  ;)

The light part I:

Checked out the corsairs' revision, those are 2.2. According to all lists I've found around the web these use Winbond CH-6.
Googled for CH-6 and found out that there's not much info for CH-6 other than for legendary BH-5 or CH-5. According to this thread ( http://www.xtremesystems.org/forums/archive/index.php/t-17187.html ):
BH take voltage and timings
CH get decent timings but wont take voltage.

So if that's right I wouldn't be better off with high vdimm board.

As no chance with ram or dividers I started fighting for some mhz extra and found some more (18mhz at least, resulting in 2853mhz total)  :crying:

actually the CH6 has a max recommended voltage of 3.1V. however, they are rated at 166Mhz, 6ns. some of them are able to scale fine with extra voltage added, some of them not. it's a matter of luck.
