I7 950 4.3 Ghz Wall

Ok so you can boot into Windows with BLK 200 that is good. Not perfect but good. Pefect would be booting into windows with 210 that would be sufficient margin to ensure a 4.6 Ghz vantage run.

Set your multi at 15 or 14 what ever you like. And boot into windows with it set at that. Then once in windows up your vTT voltage a tad and up the vCore using Vtools then only increase your multi to the max. You can use CPUtweaker to do that.

What we have to do sometimes when benching is boot into windows with the max BLk we can and once in Windows up the multi and run the bench.

Give it a try. Remember as long as your temps are still with in a reasonable range then it is all good. You are only looking for 4.6 to be stable for 15 mins.

So go for it.
 
lol - im still in the top 100 950s on HWbots CPUz results and they have had a year and a 50% price drop to catch up with me :p

personally i would be going for a high bclk and then working form a 20X multi

it seems to work best with all the 950s i am using at work.

the majority of them prefer to sit stable at 200X20 and if that can be achieved on a £75 gigabyte board then it aint too bad.

perhaps try 200X22 and up the vcore a bit
are you running LLC?

do you have the QPI LLC jumper engaged on the board as well?

that might help in this instance.

im moving this to the OC and Cooling section as well.
 
Thanks rjkoneill - that looks a very nice CPU you had/have there. It really is a lottery when it comes to the over-clocking capacity of a CPU. I have seen some from the exact same batch, clock completely differently.

Not sure if q6600 will or has succeeded but it was a good bit of fun and pretty sure he learnt heaps about his board and his set up.
 
q6600 I am not sure he would still have that bios setting at hand (maybe he does) because he did that result in June 2009 mate.

What is your max BLK on a very low multi? Have you found that out yet?
 
Outstanding mate - think your system can do that final leap to 4.6?

If I was in your position now I would drop the BLK down to 209 and try and up the multi to 22. And if that fails drop BLK down to 200 and multi up to 23.

But regardless mate you have done real well. I like the determination you have, never gave up did you.

Cheers.
 
thank you!
now the problem is the cpu v. fot 4.5 stab in need 1.6v so im not sure how much will take for 4.6 to be stab. i think 1.65v
 
If you drop some of that BLK you will not need to increase voltage I do not think. Most of the time BLK is more needy of voltage than the multi at those frequencies.
 
Try for the gold mate - QPI/DRAM voltage to 1.4 and even up to 1.45 for the fifteen minutes it takes to run the benchmark will not be a problem.

You will have to drop BLK and up a multi to get there. Go for it. :)
 
That is some serious BLK - I would love to bench that CPU sub-zero it will rock.

I am going out now - I will check back and see how you are doing.

Use the vtool to raise the multi and drop the blk you will get it. I have faith that you will


Speak later
 
Just starting out with my 950. Starting easy:

Looking good so far and temps under control.

my friend has a 980x and since 6 month is at 1.6 daily. now i manage to oc @ 4.00 with 1.24v stabil in prime 95 and 3d vantage
