Can't stable "Elpida Hyper" With i7-2600K

[PatRaceTin]

Kingston 2000 C8 (2Gx2)

Elpida Hyper ICs (MGH-E)

This ram run crazy with Socket 1156 & P55 Chipset.....

but i can't stable it with 2133 setting with i7-2600K and P67 Chipset???

(1866 CL7-7-7-21-1T run fine with 1.58V)

Would someone share BIOS configuration

Thank you

[stasio]

Yeah,me too.
Running stable only 1866 CL7-7-7-21-CR2,CR1 unstable.

Subscribed..... Interested to see if someone works this out.

Had a similar issue with Micron GKX with a DFI board, cant remember which chipset but GMH ran like a raped ape & GKX needed shoot loads of volts to do the same where as on the previous chipset GKX was the king.

Same here, I think it's CPU IMC dependent, where some CPU's have issue and others don't.

And I think it may depend on CPU clock too from what Stasio's been mentioning, IE works at 4.5Ghz but not 5Ghz+, I'll test this as soon as I can.

Same here... Corsair Dominator GT DDR3-2000 C8 won´t run stable @ 1T. Max clock which i reach was 2133 8-8-8-24-2T (but only for SPi 32M!).

My old HyperX Kit with BBSE ICs can do easy 2200+ @ 8-9-8-24-1T

Tested my old Hyper kit here. But with a bit higher voltages. Using the F7d bios. Struggled with the ram voltage. It needed 1.68v vdimm and 1.16v QPI/VTT in the bios to finish SuperPI 32M. It's just the test I did though. Not for daily use I think.

maxxx,thanks for pic.
Did you try cl.8?
Btw,did somebody know how is on Asus mb?
They have even 2400 Frequency in the BIOS!

My Kingston 2000cl8 2x2Gb whith Hyper chips stable on 1866 7-7-7-20-1T 1,8v and 2133 8-8-8-24 1T 1,8v but i use old Kingston 2000cl9 BBSE 2x1gb kit on 7-9-7-21-1T 1,7v
Asus P8P67 Deluxe + 2600k

[stasio]

1,8V?
SuperPI 32M?

[miahallen]

All of my testing thus for with 2600K ES (D1) was with Hypers....it ran just fine. But I'm having trouble with my D2....I'll try changing memory settings and see if that helps. Are you guys unable to boot, or just unstable?

With my ES....(more here)

My Kingston 2000cl8 2x2Gb whith Hyper chips stable on 1866 7-7-7-20-1T 1,8v and 2133 8-8-8-24 1T 1,8v but i use old Kingston 2000cl9 BBSE 2x1gb kit on 7-9-7-21-1T 1,7v
Asus P8P67 Deluxe + 2600k

same as mine, I need 1.7v+ to do 2133C8.
As for M4E, Patriot Signature 5 2400C9 failed to boot w/ or w/o XMP profile

[Lsdmeasap]

I'm unable to boot at all here Miahallen, 777 or 888, high voltages don't help either (ES D2)

I'm using Mushkin MGH's, and these can do 777-21 @ 2000Mhz triple on X58 with only 1.72, haven't tested to see what they can do at 2133.

It does look to me like either BIOS slight incompatibility, or an IMC per CPU issue since it works at lower CPU freq for some. I haven't tested that myself, I was only trying at 5Ghz I think.

Was testing using F7a, will try again later with F7d at stock CPU speed and 5Ghz

Your above testing is on Asus, can you do the same on GBT?

[miahallen]

I'm running on F7d UD7 right now....DDR3-2133 8-8-8 24 88 1T no issues....it's totally bench stable, but it won't pass LinX

edit - this is with my retail D2

that 2133C8 1.7v+ was on UD7. this board can do 1866C6 at 1.65v. M4E wont even post at 2133C8, furthest was 1866C8, with whatever vdimm, VCCSA/IO

Is that at 5Ghz or above? I'm leaning more towards this is a CPU/IMC issue then, as opposed to BIOS issue.

@ owikh84

I tested up to 1.82V, so it's either this CPU or it can't do it at 5Ghz, so still this CPU

[PatRaceTin]

Now i put my 2000C8 on sale

and looking to buy new kit

rate 2133 and certified with P67 chipset

[miahallen]

5GHz right now....running test after test for my next review

U could be right bro I have sold this 2600K haha.. Will grab another batch and see. Not sure what's the culprit it could be immature bios or IMC at higher clock near 5GHz.

[miahallen]

I just pushed up to 5.1GHz & DDR3-2220 8-8-8, running SPI32M....brb

did not pass.....I'm hitting the sack. I'll catch up tomorrow

[cheapseats]

found this at Asus:

" Hyper DIMM support is subject to the physical characteristics of individual CPUs. Some hyper DIMMs only support one DIMM per channel. Please refer to Memory QVL for details. "

http://usa.asus.com/product.aspx?P_I...cIU&templete=2

it's shown for P8P67 (also Pro, Evo, Deluxe, Sabertooth)

under Specification tab

[Lsdmeasap]

So it may be all about the CPU then eh?

I could see it being that way for sure, since some can do high Bclk (Man that sounds funny) and some can do high multi while others can't do either.

@ Cheapseats

Do you think that actually refers to Hyper IC based memory? Sorry, unsure if that is meant as an Asus BIOS term or something else Asus related, or actually means Hyper IC.

[maxxx]

maxxx,thanks for pic.

@stasio: I tried cl8. Pulled the vdimm a step back. I run the dimms on slot 2 and 4, if it matters. Btw, the ram I am testing is the olden Corsair TR3X6GT2000C7GT kit. Been playing with a G.Skill kit with PSC chips as well.

Good luck man do update us thanks

think it's for Hyper IC, because on the Asus qvl, the kits which are (most likely) Hyper IC don't have support for 2 dimms per channel

if it's something specific about hypers though,
i wonder if sub-timing (eg RTR_sr, WTW_sr) would help like on bloomfield

eg for 6x2gb hyper > 975mhz, i have to set tWTW_sr 6 (Auto = 4) or will not post.

[Lsdmeasap]

Ahh cool, interesting to know then.

I'll have to test those advanced timings and see if it matters any or not. I am starting to think this is a CPU IMC issue though since some users can do it without any issues, and those cases would likely mean changing advanced timings like that wouldn't matter with a CPU that just isn't going to do it.

I got 888-24 to boot at 5Ghz, but no luck with 777-24 even with 1.8V or lowering to 4.8Ghz. Either should be easily stable, let alone bootable at 2133




It's gonna suck for users if this does depend on the CPU, then we'll all have to bin for a CPU with good max multi, and good IMC, which is twice as bad as the usual crapshoot.
