Everest could be off....But you would need to go into bios and set it manually the volts and timings.. Just look on there site what the volts should be at and timings? Are you running 2Gb sticks on 1Gb? Whats the part number on those ram, just on Kingston site now

RendoR, to reset the BIOS locate the CLR_CMOS jumper and short the two pins. The two pins are located underneath the cmos battery. Just grab a jumper and short the two pins real quick. Make sure the jumper has been removed before powering on the system. Another way we be to completely remove the battery and the reinsert it. Both ways will work. I prefer the jumper because it's the easiest and fastest way.

RendoR, here's a list of modules from Kingston that display the correct VDimm. As HondaGuy suggested, it would be nice to know what the model memory you're running. Also, stability testing is something I always recommend after you have made changes...especially to memory. I don't know how many times I've lost a OS to an unstable memory overclock.

Good luck

Sorry it took so long.. The part # the package is KHX8500D2K2/4GR. I'm not sure about the R on the very end. Otherwise it appears to be the same as the one listed on Kingston's site. KHX8500D2K2/4G 4GB DDR2 1066MHz Non-ECC CL5
(kit of 2 – 2GB) 5-5-5-15 2.2V @ Hondaguy: I am using 2x 2gb sticks, 4gb total.

If 2.2 is correct, it's a far cry from what Tiger advertised. Is it safe to boost the voltage that high? Is the voltage boost mainly for stability or will it increase performance as well?

UPDATE* OK my Bios showed 1.95v so I gave it a .200 bump. That should have put me at the recommended 2.2v. For some strange reason the initial voltage reading must have been wrong because I'm just under 2.0v with a .200 bump. I set it back to normal and it shows 1.95v again. It's almost like the .200 bump didn't change anything. Is it possible the Bios is optimizing the Voltage for me? What should I do, I'm really confused now. I have a set of Corsair Dominators but the heat sinks are too tall. I was thinking of taking a dremel to them and trimming 4-5mm off the heat sinks.

Are you running bios F5? Yea make sure that you are running your ram to the website...2.2 is fine, thats why your so UNstable.......My ram is run@ 2.0 as you can see in the pic. Once you change your to 2.2 reboot and you should see it took effect...

Next pic is your timings you need to change your also to match the 5-5-5-15,
Reboot any you should be running your ram at 5-5-5-15 Volts 2.2

RendoR · 06-30-09

Hondaguy... Running F5 Bios. Is it OK for me to bump the voltage by .400? Should I notice a difference in performance or just stability? It's seems very stable @ 5.5.5.15 2T 1.95v
I'll try it. It just seemed to act funny when I set it at + .200 so I'm not sure about + .400

HondaGuy · 06-30-09

I would bump it up to 2.2 what website says...

KHX8500D2K2/4G 4GB DDR2 1066MHz Non-ECC CL5
(kit of 2 – 2GB) 5-5-5-15 2.2V

Edit: looking back a page , with your Everest test. if you change NB @ 2800 with volts +275 will be stable your score will be higher. Here is my NB @ 2800

RendoR · 06-30-09

That's what's up Hondaguy. You've been dead on so far, no reason to doubt you now. I bumped the Voltage to 2.25, ran another stability test for about 35 minutes. CPU got a little hot but it's very humid here in Baltimore. It hit 56 C, That's hot compared to yours anyway. You are on water correct? You never posted a screen shot of your cooler.

Next up is the NB. Will you be around tomorrow during the day? Id like to play with it some more but I'll wait until your free.

What's up with the Athlon 64 X2 Black 6400+ ? That seems to be what I'm competing against right now. Is that a faster chip then the Athlon X2 7850 BE? They are both Kuma cores right. Then there's the new Athlon X2 250. Why does the 6400+ show such good benchmarks? Just curious...

HondaGuy · 07-01-09

Im glad everything is working out for you.... Yes I am on water cooling, and why I never post a pic, well some things are just better kept a serect....LOL I cant give you all the answers

I should be around today sometime raining here

RendoR, the 6400+ and 7850+ are a bit different. The 6400+ is actually a Windsor core and built off a 90nm process. The 7850BE (Kuma) is a 65nm processor and is also compatible with AM2+. The Athlon X2 250 is basically a Ph II quad-core with two disabled cores and disabled L3 cache (afaik).

Which benchmarks are you referring to when discussing the 6400+?

+1 to HondaGuy for great support
