Description of Change to the Customer:
The Intel® Core™2 Duo Processor E8500, E8400 and Dual-Core Intel® Xeon® Processor E3110 will
undergo the following changes for the C-0 to E-0 stepping conversion:
• New SSpec and MM numbers for the converting products
• CPUID will change from 0x10676 to 0x1067A
• Power Status Indicator (PSI) is supported
• PECI implementation change
• New instructions added – XSAVE/XRSTOR
o New ISA extension for save/restoring context of x87, SSE, and future processor state
• New feature added - ACNT2
o Improved mechanism for determining processor utilization. To be used for more efficient
P-state determination.
• Package change to Halide free package


Customer Impact of Change and Recommended Action:
• No BIOS or board changes required for ACNT2 feature. The operating system (if it supports this
feature) will check the feature flag and enable this feature.
• No Bios changes required for XSAVE/XRSTOR. Refer to Intel® 64 and IA-32 Architectures
Software Developer’s Manual Volume 3A: System Programming Guide and Intel® Advanced
Vector Extensions Programming Reference for details.
• Power state Indicator (PSI) will require new circuits on the board to support the feature. Please
refer to the Platform Design guide document for chipset that support the PSI feature.

Well that´s it, finish testing and found my new 24/7@4200:up:. If degradation happens I´ll report back.

oki ;) that's very good to me.
Could you tell what vNB/vpll (or vpcie)/vfsb you are using ?

nb: 1,47v
fsb: 1,32v


EDIT: I check the bios and here´s a complete list:

Cpu pll voltage: 1,50v
Fsb termination voltage: 1,32v
Nb voltage: 1,47v
Loadline calibration: disabled
Cpu gtl reference: 0,63x
Nb gtl reference: 0,67x

Well thanks first!

I approximatively need the same voltages excepted the vcore :/ for my rig (see testing rig in signature) to get this: http://pix.nofrag.com/3/e/b/d83ead0f...0412664att.jpg
didn't reported any degradation yet.

Nice 8400 you got there, nearly identical to this 8500, probably need a bit more vcore due to the higher fsb, but with that fsb and ddr3 your memory must fly! Here´s what I have with ddr2:

what is your superpi 1m like? at 500x8 on an E7200 (same cpu as E8500 just neutered) i can pull 12.6.

VCore:
PLL:
VTT:

My bios names VTT and PLL something different. But i had FSB voltage set to +0.3v, and MCH at +0.275v. With the CPU at 1.49v (in windows its 1.472 idle)

After my CPU completed the burn-in phase it needed +.024mv to be
100% stable @ my initial overclock. I have since had it up to 1.6v (for brief
periods) and It has not degraded any further, and I check it regularly.

That sounds promising :)

I'm trying to break 20k again, with the same settings that give my 20k once, I'm getting 19.8-19.98k :shakes:

I finally bought a 3dmark license too :rofl:

Some of my best results with this cpu on a X38T-DQ6(bios f7b) http://pix.nofrag.com/f/8/a/b8d43f68...93253bbbtt.jpg http://pix.nofrag.com/d/f/5/5d48dd65...e9caae13tt.jpg http://pix.nofrag.com/d/f/5/5d48dd65...e9caae13tt.jpg it's a shame!!! http://pix.nofrag.com/f/6/1/3e8ee6fd...eb5d0c81tt.jpg http://pix.nofrag.com/c/1/5/f7c4468b...58c17e73tt.jpg all this is only to relate what i do atm

wow, nice fsb toyten!
<-jealous
What's your max valid freq so far?

My E8200 seem to be doing 4ghz at 1.30vish. Will try to get 8hrs orthos stable atleast. I think its a Okaish CPU ?

Anyone have anything on a q813a126? Just got two e8400 same batch.

Well..., yet I didn't wanted to play with the life of this cpu as I did with my first one which I :banana::banana::banana::banana:ed up by hanging too long at 1.7vcore, high vfsb and vpcie... I should screen arround 4750 with 1.58 vcore bios. Damn I'm pissed off with the fragility of thoses Wolfies.
@ANP!!!: be carefull, prefer a lighter stability test but that's only my opinion unno :)
http://pix.nofrag.com/f/2/0/f50210f8...045579c0a1.bmp did not wanted anymore vcore with my water because I think I have a heat issue with this cpu, I will have to concider to lap it, ...so that's my max frequency at the moment.

I'd say try them and keep us informed :up:

i have a 805a and just got a 813.. i guess ill have to try em both now.. was hoping for a 807a on the third try but i dont have that luck

Well, I can't believe it. Second SIIF board I've fried, hehe.

PCI_3 (second blue one) is deader than a door nail. Good thing I bought the 3 year *exchange no questions asked* insurance. I guess they don't have enough people hurt their boards to pay off for them.

Now I have to switch heatsinks/heat pipes back onto this one and take it in.

...frames dropped and I figured out second VGA wasn't working, just when I was about to break my 3DMark record after I had 4.58 working well enough for a bench and I had flashed a modded GT8800 SSC Bios to my SLI cards, both changes which would have got me an additional 200 to 400 points...

i have a friend who's striker just died also.. seems to common among them for my tastes good luck

Great results! I wish my ram overclocks like yours:up:

Thx dude :) yes, those D9GTN chips are great, for the price I payed them like 6 months ago it really roxx (2x1Gb 106€)

Gonna have some time tomorrow to play with it. Going into my p35 dk and replacing my q6600 l737b which did 3.6@1.3v with 1.2vid.

I got a E8400 Q807A...and I am quite happy with it :D

E8400@4000

E8400@4250
http://img145.imageshack.us/img145/3303/test1vq7.th.jpg

It can boot at least 550FSB ...but did not have time to test its limit properly.

Hi, congrats, you have a very good cpu man!

Could you tel me how do you have the correct TJunction for your Wolfdale ? I have the same 0.99 core temp beta and it shows wrong temperatures :(


Thx if you can help me on this

A few of the older Intel CPUs will be phased out including the Core 2 Quad 9450. The 9450 will be replaced with the Core 2 Quad running at 2.66GHz at $266. Other quad-core processors being phased out include the Q9300 and Q6700 leaving the Q6600 as the only 65nm Intel CPU on the market selling for $203.

Intel will also make some changes in its dual-core lineup. The company will announce its Core 2 Duo E8600 3.33 GHz processor for $266, and discontinue the Core 2 Duo E8300. The E8500 and E8400 dual-core parts will drop to $183 and $163 respectively. A new entry-level Core 2 Duo part will debut called the E7300 running 2.66GHz for $133. The existing E7200 will get a price reduction to $113.

4GHz with 1.28v only that's awsome Pseudo...
show us more of you're Q807A**
