Some QX9650 results with MSI P35D3 Platinum, STT DDR3 1600 and 2-Stage Cascade

[before]

Thx buddy This board isn't bad at all with latest bios. BTW, bandwidth might be better.

[Gautam]

Very good results Xavier and I'm glad to see you enter 3D.

Nice before ... Got to say I'm startled by this board ... it performs much higher than my expectations I admit that I have never believed in MSI motherboards after some trouble I had ... Only 2 of 'em consisted the exception of the rule ... MSI P35 Platinum (yeah the one with the heatpipe trail, fancy huh ? ) and yours ...

Hope we hear more from you !

This MSI isn't bad in 3D with 16x/4x abd 5.4/5.5ghz with QX9650 is good

Very good results Xavier and I'm glad to see you enter 3D.

Thanks bro ... boblemagnifique and I did some better results with an ES board... BTW I'm waiting for an authorization prior to post them.

Thx In fact, the board clocks very high in a very smooth way. I've to figure out what to do in order to improve that crappy bandwidth and then I'm sure it can be a nice piece of hardware.

Yeah Thanks for your OS dude lol...

[boblemagnifique]

No prob bro , Win XP 64bits isn't bad for the 3D

[ZoLKoRn]

close the neck , QX9650 , be left only two the neck brights ,
do ? ( yes sir ) ,

.... I know from this words my friend what need to know !!! hahaha...

He mean want to know your only tried only 2 core right ?

btw. neck have sound on speak seem core on Thai language, don't know why he
type " neck "

Not only 2 cores...

Yeah; a bit too cold sometimes. 0.4bar, i.e. -118C is too cold to boot. Pressure is usually within 0.6 to 0.8bar (-112C to -107.5C) during 3D load.

Here are some of my last benchies with this board. I did them with my friend boblemaginifque during the past few days. We also did better stuff with an ES board...

Nice runs But I want to see da real stuff

Bye

[before]

Yeah... Waiting for Sham's authorization to post some Blackop stuff

BTW, I've just figured out the MSI P35D3 Vmch mod and started using it. Dunno but I may be able to catch the bandwidth deficit with more volts on the NB. In fact, 1.65V (the max available) set by the bios was 1.57V actual... that's a bit low, isn't it?

[before]

OMG!! The Vmch mod gives da trick!! 596FSB on water with my E6700 L633A I've never got better than 592FSB IIRC correctly, on a DFI LP P35...

I've set the Vmch to 1.776v and managed to get a CPU-Z validation at 593FSB under watercooling. (596FSB validation failed...)

That's the highest FSB I've ever reached with this CPU under standard cooling conditions; none of the following boards did better: Asus P5B, Asus P5K, Gigabyte X38-DS5 and DFI LP-UT P35.

MSI isn't so Bad

Good Job Before

Thx marco... I'm waiting for your QX9650 dude!

Go for it!!!!!

Ok GREAT!!; will post that later today!!

[SF3D]

I want to see some Blackop results soon

I'll send P.M later today to you Xavier.

[boblemagnifique]

Go for it!!!!!

And the pics of Mobo or not ?

[dinos22]

oh common guys just post info for that X48 mobo with pics already
i'm sure it's that you are all talking about

Okay okay guys... here's the BlackOp first try http://www.xtremesystems.org/forums/...d.php?t=172458

Finnally got the trick to use the 3 stager without making the chip running out of breath.

Time is awful!! F**cking low bandwidth. BTW I may have figured out a way to improve it. Will see tomorrow.

Found something interesting on this board...

Started with a boot @460FSBx11 to perfrom Everest benchmarks and then rebooted @450FSBx11; and so on; down to 380FSBx11. Last boot was done @399FSBx11, and system was overclocked with setFSB under windows up to 440FSBx11. (Available) Timings were the same, divider remained unchanged; I've just played with PL but results are given individually.

It looks to work only with FSBSEL jumpers set to 333.









A boot at 399FSB shown to be far more efficient than anyothers. Memory Read, Copy and Latency appeared significantly improved (even with PL8).

[before]

I've got tons of things to do; so I didn't had the time to bench more on this board. BTW; I've added a second solid aluminium capacitor to the vFSB area; and made some investigations on MCHBAR coding.

So; the memory bandwidth/latency is definitely better while booting at 399FSB with FSBSEL jumpers set to 333 strap. Of course, this setting also adds more stress on the MCH, and obviously varies with CPU multipliers. That's odd indeed.

In fact, stability is quite good with 10x multiplier, but becomes bad with 13x multiplier using the exact same bios settings... Why?

I've made registers dumps to perform comparisons. Here are the differences (quite a lot for only a multiplier difference )

399FSB

MCH x13 x10
 
140  FB  FD
141  20  60 
142  1F  1E
148  61  E1
149  59  38
184  01  61
185  9D  15
188  F4  E6
189  D1  11
198  00  12
1A8  01  02
24A  C6  C7
36E  4C  C9
36F  C6  C4
52C  12  00
52D  33  21
530  65  43
531  88  66
A0C  76  77
A14  07  08
BC1  49  47
BC3  49  47
BD8  17  1B
BDA  17  1B

I'll not come to details, but the first one which shines on my eyes is offset MCH+24A (FED1424Ah). Just check line starting with 24A. In fact, as you can see offset 24A = C6 with CPU multiplier 13x, and = C7 with CPU multiplier 10x. What does that mean?

So, let me tell you. AFAIK this particular offset is where the CAS Latency (tCL) timing is hard-codded for memory Channel #0. It's a Read/Only 8bits value which requires electrical reboot to be changed. Basically, C0 = tCL1, C1 = tCL2, C2 = tCL3, etc. to C6 = tCL7 and C7 = tCL8. So, as can be seen tCL for channel #0 is 8 while booting at 399FSBx10 but 7 while booting at 399FSBx13. That's odd; knowing that I set tCL to 7 in the bios...

Then, I've tried to boot at 399FSBx13 with tCL set to 8 in the bios; and the system became stable 24A offset was correctly set to C7, just like while booting at 399FSBx10 with tCL set to 7 in the bios.

Guess there's a matter of bios coding here.

BTW dunno why, but LargeSystemCache (LSC) = 1 causes unstability again. The memory controller might be out of breath. What's interesting to note is that Spi32M can pass successfully with multiplier 13x and LSC=1 if I don't boot at 399FSB. It looks like something related to MCH data transfer limitation. I'll try with more Vmch; but I don't really like it. Actual tests were performed with 1.75Vmch (DMM).

How well does this board work with a-data memory?

[before]

I think so.
