Newer Thuban's better than the older ones?

[I.nfraR.ed]

Batches make little diff ....

To many variables per chip nowadays.

Law of science are reflected in these chips.......it's all a give and take situation.

some chips have "balanced" cores, those will never be good for a validation.....Some chips are rather "unbalanced" those will never be great at multithreaded.......

Some chips have killer core speed......enter your first chip.....but at a price....weak NB.....Then there is the opposite spectrum.....strong NB.....but then weak Core speed.

Then there is another factor that throws a curveball.....how strong the mem controller is.....think becasue your chips has good NB it has a strong IMC?

Wrong.....thats another totally diff part of spectrum.

Best you can hope for is 2 out of 4, rare to have 3 out of 4.

For benching the best you can do is know your hardware and use whatever chips suits a particular benchmark best

Good, but If you can afford as many chips as you need . It seems I have a balanced chip - strong NB, good cores, and the IMC...well, I can run those settings in the signature 24/7, but can't stabilize DDR-2000. However, with the latest beta bios for my mobo it was possible to run that frequency of the memory, but still not stable. Maybe CHIV could help?

Mine quits scaling way sooner than 1.5v, then again, I'm only on ambient water... ?

Same here on ambient water. It barely scales after 1.45V on the CPU-NB. The weaker part of my CPU seems to be the IMC, or it's the board fault, I don't know.


Tests are made this way:


OT, very nice chip, looking forward to see how strong is with cores OC.

Probly your HT OT

Yeah Dumo I forgot to recheck the Link speed after the other adjustments.

Yeah, thats a serious HTLink drop for some reason....

The voltage spike on the IMC would consern me though, did you try setting it manually OT?

BTW: What do your chipset temps look like?
I've been doing some stability testing tonight myself and man my NB is getting warm (>63c)... I'm not sure it's a problem but I don't like it...

I wish EK would hurry up and release that mobo block for the CH4.

Dave I’m in the same boat as Randi, as I don’t have any software to check the NB temp. I tried the NB volts higher but it didn’t help with more speed.

to CPU 3D06 score:
maybe its different between efectivity NB clock to cores clock. Think, every CPU clock has "ideal" NB performance clock. Example 3800 MHz/2700 MHz NB, 4000 MHz and 2950 MHz NB etc. And maybe better testing it in Cinebench R10 for it?

You may be right FlanK3r? I may try that later.

Why do you use AUTO voltages ? Have you tried with lower volts ?

Leeghoofd I was wanting to see how high the auto setting in the bios would take the NB voltage. When I increased the NB speed to 3000MHz the bios auto setting jumped to 1.5V but I didn’t notice it getting any higher as I increased the NB speed higher. I did try setting the voltage manually but again I wanted to see how high auto would take it.

OT, very nice chip, looking forward to see how strong is with cores OC.

Thanks I.nfraR.ed, not sure how good it is after testing the cores today? Maybe it needs cold?


I tested for several hours today and found the core speed to max out about 4.6GHz when testing 3DMark06 using chilled water. That’s about 150-175MHz lower than my old chip. There may be a setting that I didn’t try, one that the chip really needs to gain the core speed but so far I haven’t found it? Even being hurt the old chip is still better in 3D06 than this new chip (at least using my chilled water CPU cooling.

The link speed is up on this test. 3DMark06 CPU @3274.1 MHz 13x251.9 NB=3525.8 Memory= 2014MHz 7-7-7-18 (Chilled water CPU only)

Nowww you're cooking with Crisco OT
You've definitely got a good CPU NB there. I'd take the multi up to 20 at stock volts or a bit more if necessary,
and burn that puppy in for 24 hours. With a little time it should reach as high or higher than your previous chip,
but with better efficiency/performance with your better NB speeds.

Best regards,

[.

the binning i am referring to can't be done on air

IMC has to be good with NB cranked...I can do 2000 on any chip...not stable ...and even less so when NB is cranked.

Can't tell how balanced a chip is till you are at an absoute temp and end of voltage scaling range.....

Then is where you find the huge variance between cores and chips......

Some chips doing 6.7 on 1 core and only 6.3 on another.

Thanks for the tip Randi. I'll try and get it setup for a burn in tomorrow.
