Keeping NB and HT multipliers the same. Or at least, without too much of a drop.

First I always thought the lower the HT the safer you 'should' be to get a high HTT clock. AFAIK HT has always been at least 1 lower than NB, also because I knew ~2.2Ghz was 100% stable on the NB where as I didnt know what HT was capable off. Besides that it's shown quite a few times that a HT above 2Ghz gives you like zero performance improvement, so why bother?

But well, as I said, then I tried both 8x to get 2Ghz on both HT and NB, but it didnt boot. Then 9x to get 2.25Ghz on both and it worked.

A probably stupid question but I want to be sure;

My NB is probably around the highest it can get from default Vnb now. But I want to OC my RAM which I know it can, or at least could, do 250Mhz (DDR1000) 4-4-4. But I cant get it working. Either it insta errors or even BSOD's in Prime. Voltage range from 2.1 to 2.22Vdimm does not improve. Even running 5-5-5 does not change it. I probably should flash to a new BIOS to be able to increase Vnb to stabilize the IMC more for the RAM? Or wont this help?

When I got my RAM at 250 4-4-4 it was on Windsor F3 which is of course a complete different CPU, no IMC Voltage to worry about although AFAIK increasing Vcore marginally would help sometimes, so I guess adding like 25mV to the Vnb might help? In the end Ive of course 4 DIMMS as well.

To be sure the whole OC didnt become unstable all of a sudden Im now running on DDR667 divider again with default latencies, it works without problem.

So anyone to confirm that Vnb, leaving out that RAM might have degraded a bit eventually, influences you RAM OC abilities?

Stupid question as I said, but it's been a while Ive been busy with K10 and forgot about everything
