Intel 4.5GHz & 5GHz LinX Stable Club

**zoson** · 07-11-2011, 08:03 AM

At 4.5GHz I pulled just shy of 98Gflops, and at 4.6 I get just barely over 100. So I gained like 2.2GFlops for 99MHz(4512 -> 4611).

I'm currently working on a 4.74GHz run, and am pulling just shy of 103GFlops, so that's around another 2.7Gflops or so, which is also right in line, since I gained 130MHz this time instead of just 100.

Anyway, if we estimate 2.2GFlops per 100Mhz, and kitfit is 500Mhz above my last official submission... That's literally about 111GFlops expected. I think he did pretty nicely with 110GFlops at 5.1GHz. The discrepancy of 1GFlop is easily margin of error (less than 1% difference!!!).

I also run with ~5.4GB ram and he does 5.12GB, which can also make a small difference in GFlops.

Your CPU is under water, I assume?

Yep, I've read this a while ago.
Unfortunately it's pretty hard to determine actual GFlops of every single chip when accounting memory speed, problem size, number of used threads, cache frequency, etc. I might be dropping some of the low GFlops submissions in the future, though. We'll see.

Fantastic, now get to 5GHz! I know your chip can do it.

Looks good, especially on air!

Nice formatting, and welcome to the club!

Thanks, I think i had HT on so entry is 4c 8T instead of 4C 4T. Chip did 5GHz 1.45v until I went the avx route. AVX is brutal

Under water Vcore 1.520 underload, IMC on this chip is really crap, hence the low RAM/UNCORE

I know, there's also a dutch LinX stable club, with at lease 45min, I just use that screenshot. I was also browsing and doing stuff at the background.

Will post another with XS-rulez

It still run @max OC without more V-core. (5375)

Anandtech posted a chart today that is VERY relevant to this thread:

Just goes to show that memory speed makes very little difference in linpack, and those people trying to claim 20GFlop deficit because they have slow ram are just... not telling the truth.

Mr.z3r0 · 07-27-2011, 07:41 AM

sorry for ot:

looking for some 980X batches, whats about Batch #3013A540? any good results with air cooling?witch is the best mainboard for those 980X?

Anyone know why my BCLK drops to 99 and doesnt stay @ 100

thats the gigabyte feature, seriously

Oh thought maybe something was wrong, so I just bumped the BCLK up .2 and now its a little over a 100

Thanks

Based on your Gflops, I would have to say you do not have the latest linpack libraries or are not running Win 7 SP1.

+1

Even with a 6 core cpu running with HT on i would expect a higher Gflop's score than that.

Please remember to list your motherboards and cooling so I don't have to perform detective work on forums looking up your post history trying to figure it out...

Running Linx problem size 20000 @ 4.6GHz with i5 2500k on W7 SP1 x64

RAM 2133 127.6GFlops
RAM 1333 120.1GFlops
RAM 1333 and TMonitor running 109.4GFlops

So, zoson is right, as expected. 60% memory speed difference makes only 6% difference in GFLOPS.

And about TMonitor, it's a good thing you showed that no one shout run it during test. Just run RealTemp with LinX, then add all other in the last pass.
