Hm, I think I can confirm this, beyond 1.32V NB was necessary for me. But well I had/wanted to make 8GB 1600-7-7-7-20 work with 2.6 CPU-NB/HT. I can't change the FSB though, may very well have found the only stable spot of that setup.

hi all just been having another play today and managed 3.9 stable with my 955 be c2 (230 x 17 / 1.42v,i then tryed for 4.0 and set vcore to 1.48 first i tryed by keeping the fsb at 230 and upping multi to 17.5 but it wouldnt even get into windows so i tryed a long shot and upped the fsb to 236 and dropped the multi to 17 and surprisingly it booted into windows fine but it was not stable by a long shot blue screen after a min or 2.
so i tryed upping vcore, nb, ram volts and nothing would make it stable, so i dropped the ht down to about 2000 but it made it even worse so i set it back to 2300 and it would boot into windows fine, so i then upped it a bit more too 2400 to see if it would make a differnce and it did, with it set at 2400 it would not blue screen within the first min but it was still unstable with blue screens after half hour or so, im not quite sure what to make of this as i have always read and heard that you should keep the ht at about 2000, if anyone has any input or can shed some light on this, that would be great.

I'm wanting to install 8gb of RAM and use AOD for tweaking it, so I wanted to know if the RAM you have istalled on your setup is compatible with AOD if you wanted to use it or not. If not, could you possibly tell me what the height of your RAM is so I know what the clearance needs to be for RAM installed in the first DIMM slot (I'm thinking of using Patriot Gamer Series for AMD Black Edition)? Thankx!
Personally I don't like SW overclocking.(just my preference, altho I can see how it can be useful.) That being said you can use AOD on the memory I have. Any standard size memory 1.5 inches or less(38.10mm) will fit.

The question i must ask you tho is do you need 8Gb's of ram? It is overkill for about 90% of people.

Ummm... Yeah!!

No, I wish, that's just a validation. I've got 4Ghz & 2.8Ghz stable as my 'daily' clock, but I am still tweaking the numbers to find the best combination. 3.9 & 2.6 run with 1.4v & 1.2v, very low volts and temps. I may use that as my daily.

lol I'm not in need of it right now, but I'm just planning ahead. I'm gonna be running Windows 7 Ultimate x64 and I know that you can use more RAM on a 64 bit system. You never know when you might need it is all.

What Eclipse is probably getting at is the fact that 4 sticks stresses the IMC (integrated memory controller) on the cpu more, and can impede your RAM speeds. If you stay with 2 sticks, you will be able to get some additional speed/performance out of your RAM.

Gotcha. So, (noob question)if I did go with just 2 sticks of RAM totalling 4gb, can I install them in the 2nd channel slots (DIMM 3 & 4) without having any RAM in the 1st ones?
post #2460 of 9641
yes you can that is how I have mine setup
