2500k RAM stability in memtest

post #1 of 5
Thread Starter 
Title a bit misleading, the problem is in IntelBurnTest
Hey guys. I'm building a rig for a friend of mine, and I am currently overclocking it.

The specs are:

2500k
Asus p8z68 v-PRO
Corsair vengeance (2x4GB) 1600MHz 8-8-8-24
Gigabyte 570 SoC
Corsair H70 with silent fans.

Now, using Miahallen's guide, I started by setting everything stock, disabling throttling, and using X.M.P, to set the RAM settings.

Then I started booting, testing with memtest, upping VCCIO until no errors in a single pass. Then boot up, and start IntelBurnTest, do the same upon error.

Problem is, I'm at 1.2V VCCIO now, and I still get an error once the second pass finishes. Any idea what I'm doing wrong? Memtest passed already at 1.1

My current settings are in attachment. Don't mind the Vcore, it's just there to make sure that ain't the problem. The turbo multiplier is at 37, RAM at the specified values.

EDIT: I'll be going out for a bit now, and I'll let MemTest run in the meantime, to let it do a few passes at 1.2 VCCIO. I'll report back later.

RUn the whole thing in stock set the RAM to XMP and run IBT/ prime for a few mintues to see if it passes.

Post all your BIOS settings and then we can take a look.

One more thing, you shouldn't need to increase vccio that much, that is probably what the problem is.

Well, that's exactly what I did to begin with. All the way from 1.05 VCCIO, and then I kept upping the VCCIO, since the RAM should do the speeds at the stock 1.5v.

Now, I have set the timings at 8-9-8-24. And it seems to be doing fine at stock everything.

I guess I'll just settle with that. It seems like the RAM just won't do 8-8-8-24 that it should.

I recommend try the following without increasing the vccio for now:

Try 8-8-8-24 with the 1866 strap and leave the vcore on stock (1.5v) and again work your way up from 1.05v vccio. Test with prime blend, you'll either get a roudning error or bsod, make sure you note what the bsod code is.

leave the reset on stock

Report back when you can.

By the way it could more than likey do 2133mhz, with a small voltage bump, you could try setting it to 1.65v with the same timings and try the 2133 strap. If it fails you could always loosen the timings a little to 8-10-8 or 9-9-9.

Right now I'm testing at 1600 8-9-8, finding the lowest VCCIO for stability. If I have time, I'll try out your suggestion, thanks a lot

My buddy really wants his new rig, and seeing how little impact the RAM speeds will have, I think this is easiest.
