Ok here is a succesfull pass at 4.5 full memory at the lowest volts i could get. I tried with HT on but my water setup wont handle it.

Try dropping your CPU PLL voltage down to 1.425v. It will drop your cpu temps considerably, and will probably get you a higher stable clock.

Do you leave IOH PLL at 1.8?

Yes you do.

I don't know why most mobo's default the CPU PLL voltage to 1.8v.
When your going for a high clock with good cooling, it will easily run at 1.425 with a much cooler cpu and much better stability.

I tried dropping CPU PLL. I dont have 1.425 in bios. Anything lower then 1.8 are whole numbers i.e. 1.7, 1.6, 1.5, 1.4. I have selected 1.4 cpu pll. Also I droped qpi Pll to 1.2 as im sure that was not need and lover looked while I was trying things. Booted into windows and make 1 pass and bsod with a 124 error. I bumped up vtt 1 click and retesting again.

The default for QPI PLL should be 1.1v. As a rule both the QPI PLL and IOH Vcore should both be set to the same voltage.
Sometimes both need to be set to 1.4v/1.425v, especially when above 200 BCLK.

Ok so your saying set cpu pll to 1.4v and QPI pll and IOH core should be set the same 1.1v and keep the same when raising them?

Edit - I reread your statement and understand what your saying.

pll voltage depends on ure ram speed ure running
so ultimately depending on ure ram multi

1.65v is still good up to 2160 bclk 216..
but temps difference.. dont think so..

Good clock Anth Seebel :up:

I would of thought you should be able to do the same clock with HT on as well ?

Rejected, sorry. Not guessing the actual frequency.
Read the rules.

Updated, but the next time make sure to complete at least 20 passes. I'll make an exception, pretty sure you'll be back with a better submission. ;)

Also, do you only have 3GB of RAM? Using just 2560MB is kind of weak, tbh.

cheers zalbard, seems like theres abit of confusion as i noticed a few other submissions accepted running the 20th loop so i assumed that was how the rules read.. no worries next time il run an extra loop :)

yeah i rather do other stuff than watch linx , thats overkill for me anyway.. ie. nothing crashes

^^ Nice run:up: 1.360v, you have a good chip.

@zalbard, Great job with this thread. Ive had a lot of fun trying to get different chips to make it to 4500.

Would be great if Lynnfield were seperate from the Bloomfield under i7's.

Update, broke 30 GFlops

Need more cooling, maybe a corsair H50.

Very nice run.:up:

The H50 works great with the Clarkdales, the backplate provided is a pos though. I have been using the backplate that came with the XT waterblock.

@kill a wat - very nice! - nice low temps!
what is your ambient?
06-16-2010, 10:07 AM

Cheers :) unsure about ambient but it is pretty cool in Sydney at the moment definetly below 20 deg. Bought the CPU second hand and it was also the coolest running of 3 980s ;)

I know it is out-of-date for Bloomfield, but I'm afraid I won't have a chance here for Westmere:shrug:

4606.6 = 219.4x21 @1.3625v, water cooled, rampage iii extreme
220+ bclk on R3E results in weird graphics corruption and corrupted gpu<->host bandwidth:down: which never happened on UT or UD7.
CPU seems fine and might get a bit further though.

vtt is probably an overkill, more than enough for 2000 7-7-7 linpack-ing.

@ kill_a_wat
how were the temps with LinX?

These were my 4.4 w/HT and uncore overclock voltages so they could probably be lowered.

Am I missing your 4.7GHz i5 run, btw?

Nice formatting! You're in! :cool:

0.15ish difference isn't huge, though, nothing to be worried about, it's normal, and is actually worse for most boards. Nice run! :up:

Any idea what batch number you have? Your vCore is VERY low for these clocks! :eek:
