The CDT and copywaza lab

[massman]

Thanks mate.

No effect at all? Are you talking about how the graph pattern looks or the times in seconds? Your subtimings were changing too so I can never be sure what is causing the lowering of times because those were the exact subtimings which were giving me lower/higher times.

Actually, the only subtimings that changed are the PL, Write to precharge Delayed and Write to Read Delayed .

[KTE]

Yep, that's what I'm referring to. Those three and tRFC are the only ones which give me biggest gains in 32M.

BTW I found out it was the damn CPU for sure which was FSB limited to 476 bootup and 480 SetFSB, and not the board for sure. Might get another chip (definitely the E6850 this time) if that's the case then, depends what free and available when I go to visit.

[kiwi]

Of course. Any P35 chipset (combined with more or less normal mb) will do 500+ easily. Hell, I'd say even 550+ with a slight voltage bump

[dinos22]

if you are still on Gigabyte board they will pretty much all do 600+

such as P35-DS3P or DQ6 boards as well as X38 ones

you just have to have the chip capable of that FSB

For CTD and A64, try MAXMEM=104 and three files of 136MB

In my experience, Maxmem of 104 will not work with 32M. But i will try one time more..

Sure, 32M needs like 250-260MB of RAM

That is/was the problem, bcs. back in the days i benched always with pagefile disabled.. Under this conditions 104 will not work.

As i said before, i will test it again with pagefile enabled.

Now, Super Pi reacted VERY different today with this RAM (same everything else) than with the other on other days. It was VERY slow compared to the Corsair RAM at the same settings, same board and everything which sounds wrong but its fact. Actually, even at slower Corsair RAM settings Crucial RAM used was just not even close to Corsair RAM results. Which makes me say "WTF"

simple explanation is the ram have different SPD settings.. minor tweaks or differences can effect times

[KTE]

Are there any internal RAM performance settings that we can never change? There must be something.

Thanks for the info, interesting. I won't be booting the C2D for a while after tomorrow so if you want me to test anything on the Abit, let me know quick You guys will have to continue the testing without me now.

I've been using the Abit for a day. Max stable FSB all stock volts: http://img144.imageshack.us/img144/1...400idleve3.png

1.350V BIOS is 1.312V Windows 1.288V load.

DS4 is a very good board, I'd recommend it I'm sure it can get plus 550FSB, NB runs so cool at max volts it's unbelievable. Beware if you have an ATi GPU though, overclocking can only be done once you uninstall the GPU. My Sapphire GPU is locked too, non-ocable.

Good news is that I was on phone with 'ol uncle earlier and he let me keep all the stuff... including the AMD stuff... free Even better news is I'm going to sell them=> probably keep X4 build and the DS4 till a new Intel chip.

Bad news is I could've got 4x Powercolor 3870 800/2240 today to play with if I had a PSU. This ones the only one I have here till I sell it, it doesn't even have enough connectors for this C2D build and it's 330W. Rails are low (hi-pots) although rock solid but that's Seasonic for ya. I'm kinda dissapointed.

i guess playing with the SPD...i remember Dumo testing some corsair C3 vs team xtreem OPB ram , same bios settings , same FSB...the team xtreem was faster in 32m and a tad in 1M. check the thread out here...hope it serves what you are looking for.http://www.xtremesystems.org/forums/...highlight=dumo

[KTE]

That's exactly what I was asking and looking for Enoc. Thank you mate.

So, different RAM, different efficiency at same setting for everything. That's what I was seeing with Corsair RAM vs Crucial. Corsair (ProMos) were faster than Crucial (Micron) at same everything.

OS + SP on 7200RPM vs OS + SP on IRAM

IRAM wins by 0.140s in 32M

No difference at all even though all OS dll and SP files are on super fast storage

That's exactly what Hipro5 said.

Thanks for testing.

[KTE]

Thanks for the test.

Then this just shows even more the effects of diffrent RAM models, boards and OS.

[kiwi]

Well, 2k3 is supposed to be better for SP but the problem is that it must be correctly tweaked to be faster. At stock it is not faster than XP SP2/SP3

Tested Corsair 6400C3 vs Crucial Ballistix 6400 (both are Micron D9GMH). Difference in 32M was 0.06 seconds 32M times at 515x7 1:1 PL=7, 4-4-4-4 were 13m11.594s and 13m11.656s, respectively.

[KTE]

My tests were the Crucial 0.2s behind in 1M and over 8s behind in 32M. You can see it earlier in this thread if you compare times of both RAMs at same speeds. Crucial with lower timings couldn't match the Corsair.

[KTE]

Maxmem made 0 difference with Phenom.
Copywazza didn't impact Phenom 9500 at all.
CDT made 0.234s 1M difference with Phenom 9500 without Maxmem.

2695MHz - 1960NB/1960HT - 490 4-4-4-4-20 1T: 28.407s
2706MHz - 1968NB/1968HT - 492 4-4-4-4-18 1T: 28.250s
2750MHz - 2000NB/1000HT - 500 4-4-4-4-20 1T: 27.813s
2750MHz - 2000NB/1000HT - 500 4-4-4-4-20 1T: 27.579s (CDT)

Can you say "PP"?

[mrlobber]

Can you say "PP"?

What's "PP"?

Nice to see the CDT we know about still impacts Phenom 1M.

[KTE]

Cycles taken by processor to complete 1M calculation.

Comparison of v.similar 2750MHz 9500 run: 28.579s
He has much faster NB/HT, should be at least 0.2s quicker than mine since NB affects perf very much with Phenom.

No further testing on CDT ? ... Not working with the yorkfields / wolfdales or ... ?

[TheKarmakazi]

Anything further here? I have read this thread with intense interest. Has anyone other than those previously named gotten CDT to work? MAssman, KTE, mr.lobber (based on your excellend spi results this week I would guess you have?) any of you got it?

[saaya]

from what i know, yes, there are techniques that help, but they are very inconsistent and... the boost was not as big as some people thought/had hoped.

[massman]

The main reason why it has been so difficult to reproduce the results is because of the lack of the correct way to perform the CDT. Maybe I'll restart my tests soon, dunno ...

[eva2000]

i long gave up trying CDT LOL
