I will try to get under 7 30 but it's not that easy.
How about sending me some cas 6 PSC :)

OH flip the OCZ SSD I was using to boot XP has just died.
BIOS doesn't see it anymore

I have that issue with my Vertex 2 as well... BIOS sees it roughly one time in three. I have to just keep rebooting until the drive is visible.


Very nice time by the way... I'm not sure I can beat it to be honest... Currently a few seconds behind, but I haven't done any benching for over a week. I am getting better scores with this TridentX set than the 7:37.3 on the leaderboard, but haven't been saving screenshots yet since I'm still tuning.

I'm back in the UK now but I need to work long hours this week so I won't have time for pi :( Saturday / Sunday I will have a good crack at it, but it's going to be a tough ask I think. My RAM can't quite do those speeds at CAS9 either (1322Mhz is fine, 1350Mhz nope - at least not yet). Anyway, I'll post my best time on the 30th and we'll see where everything lands :)

Nice to have a target though :)
 
What on earth.

Save overclock profile that I used earlier
Install XP on my spare drive, move CPU-Z etc over and tweak OS etc
Reboot
Load overclock profile.
Boot into XP attempt to run SuperPi - error in round

wtf these settings we're fine half hour ago, swap back to win7 drive reboot run superpi with same settings in 7...Guess what error in round.

This motherboard hates me :(
 
RAM is at the edge mate.

Let it rest and try again. Also dial in your settings. Like with my Trident I start at 2800C9 then 2933C9, then C8 then tune thirds then run. Only reboot or run 8m to dial in. But dont jump to top clocks. Force memory training several times!!!

That would make sense, but I'm not being hard on the RAM at all. 7-9-7 @ 1656mhz instead of stock 6-8-6 @ 1600mhz. Plus i've got a 120mm fan blowing down on the ram aswell.

Was booting into windows @ 200FSB then upping it 1 at a time to my 207FSB target with a 10-20 second pause between each increase

Edit: started being a little more delicate in my efforts and have found that if I try any more than 1.7v on the ram I start getting errors even at stock speeds.

Currently passing 8M @ 9-10-9 1744mhz.

This is keeping the nb multi at 10x so I can find my max ram frequency, I'll then work the same approach for the timings, and finally the notthbridge frequency and hopefully I can pull something off now I seem to be figuring out the issues.

Currently working in 48mhz bumps on the ram as this gives me my optimum clock speed. Will dial it back when I hit a memory frequency wall and ignore optimum clock to push the ram as much as I can

Got under 7.30 which was my personal goal.

8pack how about some tips ? or is that not allowed.

Little upset, all was going well last night, had the memory 32m stable at 1744mhz with loose timings, until I discovered one stick of ram wasn't actually seated properly and I was running in single channel :(
 
tried single channel/one stick with that board pcb? supposed to boost ram performance by 10% with topography on that board in single channel

Let's save the tips for after the competition :p

I don't want you getting too far out of reach!

Nice score though...

So you aren't going to post any intermediate scores ?
Thread will be real quite if we all wait till the 30th !

I have read through quite a few Super PI tweaking threads and none of them mention the real tweaks :)

No matter I have worked most of them out myself.
Of course I won't be sharing till after the 30th.

NOT EXACT IN ROUND is out to get me

Heh... I'm not running pi today - need a good few dedicated hours to do it properly. Might have a go one evening this week if I get stuff done, but I've pencilled in all of next weekend for a proper session. I was down at 7:31, for what it's worth, but I'm planning a 'suicide run' with more voltage to see what I can squeeze out of the RAM at the end.

Finding the right balance between speed and tight timings is tough... and The Great Enemy (aka 'not exact in round') is always lurking. Always watching. Ready to strike misery into the hearts of hopeful clockers. He likes to hide and wait until about loop 20 to give his victims a chance to build up hope. But I will defeat him...

I'll post my progress on Sat and Sun I promise.
 
Goddamnit... :p

Looks like my schedule next weekend has opened right up. I'll do some runs to post a time but no way I'll be able to match that.
 
You need to do things the tweak info doesn't mention because basically it was written when dinosaurs ruled the earth.

Good Luck
 
Well, even if I discover these magical tricks I still can't match your memory clocks - that much I'm certain of. It won't post at anything over 1350Mhz CAS9 1T, and my board won't go over 102 BCLK either so I'm confined to a 40x multi. I think the IMC on my CPU might be limiting me - the chip itself is a terrible clocker (4.2Ghz max stable, 4.5Ghz max pi stable). I could get another one I suppose - I was going to wait and see if I won this kit first, but no reason to wait now. Don't want another dog chip though!

Anyway, I'll just concentrate on posting the best time I can for the sake of good competition :) I won't be able to get sub 7.25 on the hardware I have. It's been educational though, particularly on the OS stripping / system cache optimisation side of things.
 
My chip is also an awful clocker.
4.2 Ghz is OK any higher and I cant put it under any appreciable load.
Needs too many volts and gets real toasty

I am scared to buy another one as it may also turn out to be a real bad clocker.

Same here... I don't need / expect a super clocking chip, but one that is at least average (say 4.5Ghz capable at 1.28v) would be nice! Another dog chip would be a real blow especially as I'll lose 60-70 quid from selling this chip, considering postage etc.

Out of curiosity, did you get your CPU from a certain retailer whose name is a type of classical song?
 
Update: 16m44.766

Took things back to basics and the times are dropping :)

Interesting my times are quicker than Kei until loop 12 then it starts to drop off again.

Edit: another 2 seconds knocked off my time.

I love this mushkin ram now. Still can't work out why more ram voltage makes things less stable. But these runs are being done with 1.65v at nearly 1800mhz with the timings only marginally looser than stock.

Edit 2: That's Kei's time beat, now to see if I can lose another 4 seconds and beat PCZ

Edit: This is best I'm going to pull out the bag, sub timings refuse to go any lower than I had them already. Wish I could find that other second or so to take the AMD crown but I'm not going out and buying a Thuban chip for that.

Edit 4: just tried again at 7-8-5, was look good till the pesky not exact in round showed it's head. This has all been done with 1.65v may I add, more voltage seems to defy logic and cause more stability problems.
