EVGA Classified + 920 DO - goes 5GHz+ Wprime 1024!!!

[Raja@ASUS]

you'll have to boot around 221~222.

Only voltages you'll need to fiddle with for your chip are CPU VID, VTT, Vdimm

Those 3 will be completely unique to your CPU and will also vary with temp

For 3d over 233, set IOH to around 1.30V. You can pass 3d mark 06 upto around 233-234 BCLK. 231 is rock steady for both 06 and Vanatage oon this CPU. 233 takes a few reboots at times.

QPI COMP and CPU impedance - again will vary with temp and the IOH.

I left all oter voltages at stock, no need to change them from their base values - even upto 245 BCLK.

thanks raju, I'll have a play around but at this stage Im only about to boot at around the 214 BCLK mark...might be CPU limited.

[Raja@ASUS]

are you on air or cold?

[gaidin]

Im playing around with it now on air (well air and a whole lot of dielectric and kneaded erasers hehe) but have the cascade waiting here to fire up when Im comfortable I know what Im doing with i7

But I thought that as long as Im using low CPU multipliers (Im currently at x14) I would be able to test the BCLK and QPI maximums. Im probably missing something though

[Raja@ASUS]

some chips only scale well under cold for BCLK. This one won't go past 230 on air.

http://valid.canardpc.com/show_oc.php?id=553271 clean validation this time

another 1m

[gaidin]

getting close to cracking under the 8 sec mark

also hitting over 240 BCLK is amazing

[Raja@ASUS]

5G's 32m, untweaked.

[SAE]

Wow. Amazing approach^^.

That little d0-b4st4rd goes like hell with the classified!

[Raja@ASUS]

Thx SAE, 1 more

[gaidin]

after Ive been through the learning curve with tis chip I might go looking for one of your batch

[eva2000]

yup 38xxBxxx batches seem to be a bit better than A batches

[RNeon]

920 DO

rotary cascade - evap -108

EVGA CLassified, I think the result speaks for itself..

8 thread - 5GHz on a 920..

hello,

where did you found the Bios Version from April the 21 ? my latest Beta ist from April the 17? do you have a link for this bios? thank you

[Raja@ASUS]

The BIOS is beta status - not public yet. As soon as EVGA approves after full in-house trials they'll go public with it.

Raja

are there any good changes with this Bios version?

and please maybe you can post a biostemplate with your settings for 220bclk and above ? thank you

[Raja@ASUS]

THe newer BIOS adds Dram Vref and also individual RTL control per memory channel.

On the template front there's not much to say, 103 PCi/e will get you upto 230. Over 230 you need a minimum 108, 110 will push past 240 BCLK if your CPU is capable.

The only 3 voltages you need to wrry about vary so wildly from CPU to CPU that it's almost impssible to use the settings of one on another (Vcore, VTT and VDimm) and expect the same results. Play with CPU Impedance and QPI Comp for stability at high BCLK, again this varies according to the IOH and your CPU.

[gaidin]

ahhh so I need to mess with the PCIE freq too?

Might have to take a look at that cause I am otherwise limited at 4.65G

[Raja@ASUS]

Yes you do need to offset PCI/e. Make sure you do it from BIOS to create the offset necessary during the boot cycle to create BCLK headroom within the OS.

[gaidin]

Many many thanks to you raju. I upped the PCIE speed and the CPU just took off



http://valid.canardpc.com/show_oc.php?id=553974

[Raja@ASUS]

No probs, you should be able to bench upto 240 quit easily, and possibly even better the stuff I did. There's nothing to it really.

Nice Chip M8

What vcore was used for this ?
Moreover, what is the Batch# of the CPU?

Thank you for help i´ve put the PCI/e to 101 for 220 BCLK. i´m priming now but i cannot run the 221 bclk. these are my settings at the moment



thanks for help

[Raja@ASUS]

If running a D0, you should have plenty of overhead to scale on the 21x multi without chasing 221X19 for 24/7. I'd use the 21X multi and start off with 200 BCLK. I bet you can run 4.2GHz with around 1.24V load Vcore too.

yes i can. I only test the BCLK at the moment. Look BCLK 221 seams to run at the moment

@The-Fox, thanks mate

I think its probably only typical of the kind of overclocks we can expect of the D0 stepping...but this board is just so nicely built and lets you push the chip relatively effortlessly!

This validation used only 1.425 vCore and the CPU is Batch# 3849A837
