Guide to Overclocking the Core I7 920 or 930 to 4.0ghz - Page 16

post #151 of 1477
Im looking at buying a dell adamo laptop
It has a SU9400 1.4Ghz 3mb l2 cache 800mhz
The superpi times are: 29 66 1567 1m/2m/32m
this is 2 slower than i7 920

Does this mean its exactly 2 times slower in practice?

In theory i7 is at least 10 times faster

Thanks

Hello,

I was using a I7 920@4,2(with turbo mode) with a ASUS P6T motherboard with a 2x1Go PC 10800 running very fine.

I bought a 3x2Go Trident series PC16000 kit.

My problem :

I can't run my usual overclock with the RAM set to 2000Mhz

The computer boot with :

The proc at 3,2ghz and the kit at 2000Mhz.
The kit at 1600Mhz and the proc at 4,2Ghz

Can I make the proc at 4,2Ghz AND the RAM at 2000Mhz working together ?

Thanks

PS: I set the timings to there good configuration (9 9 9 24) and the DRAM Voltage to 1.66V.

I tried with DRAM at 1.8V and QPI/DRAM at 1,45V with no resuslts.

Thanks

Yahh.. I certianly need some help =(

I read through this again, all day, got home, and still felt lost.

I did something to my machine, and my 3d06 score went from 17000+ to 10k!!!

No idea what happend to that score but I am trying to simply break 20k.

So need help here, my target OC will be 3.6ghz -- Ram 1600 - 1866 mhz (pretty sure these can handle 1866 ~1.65 with cas 9)

Now the thing is This motherboard confuses the heck out of me.

It is the Stock version, original Deluxe Model, not V2, no updated bios or anything to that extent.

The trick here for me is that I want to overclock well without much increase to voltage, i do not like to break past recommended specification's and was not sure if I should use the Load Line Calibration or not. VDroop sounds like a horid problem to have for a stable OC.

What I need to know is the exact settings to turn off for the Asust P6T Deluxe, what settings to keep on.

What to change From Auto to What.

And for the memory, I am completely Lost.... I haev No idea what the F to set this thing to, I just completely friggin lost here =(

You should be able to do it (assuming the ram is good). Run memtest86+ for a while(few hours) on the ram at 2000 and cpu at 3.2. If all is well, I'd start your overclock over again. You may need to up the qpi/uncore or the ioh or the vdimm (past 1.66). When you run the ram at 2000 it means your uncore is at 4000 which is pretty high. You might be better off running it at 1600 with tighter timings.

Is it d0 or c0?

D0 disable turbo, set the multiplier to 21x for cpu, 8x for memory. Set vdimm to 1.66 ioh to 1.2 and qpi/uncore to ~1.3. Set cpu vcore to 1.30 and your bclk to 175. That will do it.

If it's c0 just bump the vcore to 1.33 for now. You shouldn't be able to fail with those settings.
