8 Packs 4ghz 32m Challenge win full Haswell 4770K Bundle.

Thanks, its been a long hard struggle to beat Kei and PCZ but I got there in the end

I think you deserve the new rig not the people who already have one.

I think you deserve the new rig not the people who already have one.

Unfortunately won't happen unless whoever wins is feeling very generous,or 8 Pack/OCUK feel extra generous and decide to give two bundles away.

I wonder how much 8 Pack could beat me by with a similar setup.

955BE, 1600mhz RAM and no sub-zero cooling.

Good job on passing pcz. You had to buy new ram to do it though, which kind of defeated the point. if I'd bought some fast ram I'd probably have a similar time. The biggest challenge is to see how far you could have gotten with your original ocz ram. We both made a lot of progress though, I started off at 18m 05s in the beginning.

 

[Frozennova]

My first time was 17m22s but I had roughly dialed in a couple of things.

Can't really count buying new ram as I'd been meaning to buy another 4gb for a while, this just gave me the kick up the backside to do so.

I'd have never got anywhere near with that OCZ stuff. It didn't clock for toffee

Great score, you just posted.
10/10 for effort.

Hadn't realised that I had a big target on my back.
I thought it was Kei and yourself that were in competition.

My focus has been on a different platform.

I have run SP on the 965 again and posted a new score for you to chase down. (see below)

Note: The tRC setting i was using before was far too low and wasn't being set properly, most likely AUTO was actually being set.
I set tRC to a sane level and tightened the SUB timings.

That's easily sub 8 mins with xp and a couple of os tweaks Biffa.

Stripped Win7 down as far as I could and got a sub 8min time:

 

[Frozennova]

Dam, it was me an Kei in competition but i managed to break through his score a while ago, you became a target when I started getting down to around 16m47s as you we're the next quickest.

I knew you'd been focusing on Haswell so was hoping you wouldn't post another amd time. I might just be able to better that slightly. But I won't be able to till Sunday evening.

 

[Duff-Man]

Played a little pi last night

Spoiler

Still a long way off PCZ's time, but I'm happy with the time for now




Frozennova - I'm sure you have the will and patience to chase down that time (assuming you have enough time to tweak of course!). You can find three tenths somewhere!

 

[Frozennova]

I'm sure I can somehow, I'll have about 5 hours to play on Sunday before the competition officially ends.

Those 3 tenths are going to have to be a combination of luck and sub timings I think.

I know I'd easily do it with another board as PSC scales well will voltage but I still can't seem to get it to work right with more ram voltage. The same settings as my last run but with 1.7v instead of 1.65v give me not exact in round errors.

And I'm pushing pretty silly northbridge voltages as well, to get 2912mhz northbridge stable at these memory speeds aswell.

Edit: gutted there won't be any Haswell for me as I've pushed dammed hard for the result so far.

 

[dlknight]

I only have 2 sets of green and one set of the C10 TG's so hardly a large enough sample to draw conclusions.

LOL - I spoke too soon, managed to get a couple of seconds quicker with the Team Group RAM

I think my motherboard is holding me back as it has limited options for RAM overclocking compared to the ASUS ROG boards

Anyway I think my i5-2500k has given all it can give so over to a i5-3570k for some tweaking tomorrow

8m 08.016s



My MSI Z77A-GD65 only lets me tweak the following timings (no tREFI or tRC) -

CR
tCL
tRCD
tRP
tRAS
tRFC
tWR
tWTR
tRRD
tRTP
tFAW
tWCL
tCKE
tRTL

tRRDR
tRRDD
tWWDR
tWWDD
tRWDRDD
tWRDRDD
tRWSR
tRRSR
tWWSR

 

[Frozennova]

What options I've got available makes yours look like a huge list. Mine is limited to the first 10 that you have

Posting my final Llynfield, Sandy Bridge, IVY Bridge and Deneb results.

15 750
Couldn't quite crack 9 seconds
Spent all day trying, the 10x max memory multi on the 750 is quite a handicap.

X4 965
Found this chip to be Very finicky with memory voltage when running over 1600Mhz.
Takes a while to find the right combination of MEM, CPU VDDA and CPU NB volts.

Dam PCZ I think I could have slightly better the old time but not that one.

Not on this board anyway. By finicky do you mean it would let you raise the ram voltage?

My problem is that any voltage on the ram past stock actually makes things less stable. I'm on a budget board so have no Vdda voltage option. I can run close to 1600mhz or a little above with 1.8v but with higher memory frequencies I can't go any higher.

 

[Kei]

Just how many systems do you have, PCZ? I've only got my phenom, AMD64 and a Yonah laptop to play with. (or some real antiques in the loft)

My motherboard doesn't have VDDA either though I've got CPU PLL voltage and DDR VTT which i've left alone as i've never needed them. (VDDA is the asus term for CPU PLL)

Spoiler

It's the same story for adjusting things like data drive strength. It's out of my depth so they get left on auto.

[Ethermaster]

Its the final day to get your results in good luck everyone in beating PCZ's time....

 

[Duff-Man]

Okay - let's get the ball rolling.

Nice
Who said 7.30 was hard ? Oh wait it was us !!

I have my final IVY run to do then I will get back on the Haswell.
