idk.... most likely not.

hmm, i'll do some more testing and keep you guys posted.

Thanks for the help FIT

i've run 1600mhz stick at 2133mhz.

you should be able to run 1800 at least with yours.

that certainly inspires me haha. Thanks dude. I'll keep you'll posted!

Guys, got a questions

My RAM at default is designed to run at 1333 MHz. Right now it is running at 1524 MHz. What can I do to increase RAM stability without lowering the divider from 2:8 to 2:6??

I know that is my problem going from 4.0 GHz to 4.1 GHz because I wont boot like this. I drop my divider and it goes into windows and is stable for a long time, then it'll just take a slight bump in voltage to stable out the system. But ram seems to be holding me back in this case.

ANy remedies to this other than dropping the divider?

My DRAM voltage is 1.66v right now.

Is this the ram you're using?

CORSAIR XMS3 4GB (2 x 2GB) DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory

Assuming it is then the question is how much more than 1.6V will it take? If I was using this kit then I'd gradually raise the VTT up. I've seen screenshots of the VTT all the way up to 1.6V. The question is what is the max safe VTT?

If you don't want to take that route then get some better memory.

hopefully i'll be getting some better ram soon

no, this is my RAM

THanks.

hopefully CP will take mine on friday.

I'M HOPING TOO!

Well Had to drop the divider, wouldnt boot no matter what.

So here is my best W7 run on a single 4870, quite impressive in my opinion.

In this post saaya says that 1.65V VTT is fine afaik!

Core i7 Vdimm/VTT Graveyard


This is my latest testbed...
* DFI LP UT X58-T3EH8 (R.A56) 01/23 BETA BIOS
* Intel Core i7 920 3837A902
* Corsair Dominator 2GB DDR3 2133 PC3 17066 Dual Channel Kit

I've had the VTT up to 1.48V but I've seen others going higher. What you use depends on whether you're prepared to loose it!

just dont kill it like i did.

CP, did you try to increase the tRFC to 74? And tRC to 33?

The Uncore should stay at x17 (3400MHz).

And with 200 baseclock, your ram should run at 1600MHz.

naw I havent. But i'll try.my uncore is 16x. I'll try 17x maybe allow my ram to run at 2:8 since this way it wont be at a 1:1 ratio like when my uncore is at 16x.

Nice David.... real nice!

After a little testing........... 4411mhz vcore:1.45v vtt:1.38v Qpi:1.36v
Cpu is lapped and cooled by a ek Supreme
This little biostar is very surprising!

whats your ram speed?

we cant see the pic man,its too small..... try again.....

 

[Chicken Patty]

hey bro thats a nice overclock. Did you run super pi with any windows open?

 

[The Haunted]

I ran superpi when the computer was idle, but i have HT on maybe thats why i get a bad score.

thats why, HT off you'll drop down a good amount
