E8500 - Q745A554 - VID 1.125v - AIR

[AriciU]

I bet this chip can SPI higher then this. My ram is limiting me bad at 510FSB. I get errors in SPI at 6 x 509 and upwards.... I'm gonna get some Ballistix in 2 weeks or so and will push it more.

Anyway, here are the results. Ignore the low multi in CPUZ, i cannot disable EIST with the latest bios from Asus, it was set at 9.5x at all time.

Setup:
Asus P5K-E /w 1006 Bios
Gigabyte 8800GTX @ 660 / 1674 / 1107 (GPU / Shader / Ram) /w 171.16 drivers
2GB Geil Ultra PC6400 @ 1:1 5-5-5-15
Thermalright Ultra120A
WinXP SP2
Room temperature - 24C

Max Spi 1M @ 4829Mhz

I didn't go for max clocks because of my ram limiting me....

This CPU runs very hot btw. Currently Orthos-ing for about 30 mins @ 4300Mhz @ 1.48v and i have around 68C.

[AriciU]

These will be my daily settings.

Not bad for air.

Room temperature - 24C

You mean "-24*"
or "+24*"
Cos if second one, you have an extra extra effective AIR cooler giving you 40* Idle after 1M Spi with 4828@1.66V

No way man, my water cooling is reading 51* idle with 24/7 freq and 21*C ambient 4400mhz@1.52V

Yeah, +24C of course. I'm not some damn eskimo. 40C idle is a Core Temp bug. I get 40C idle even at stock frequency and voltage.

Orthos stable for an hour which is good enough for me. Don't want to stress it anymore at those high temps.



The bad news is that i've got some Ballistix to test with(thanks bonzo_catalin). I tried them first by setting a divisor and they worked no problem at 550Mhz @ 4-4-4-4. However, i then set the CPU multi to 6x and tried the thing at 510Mhz FSB 1:1 and no go. Windows just crashed.

So it's either CPU fsb wall which is not likely... all i've seen went up to ~530-570+ or it's either my mobo limiting me. I'm guessing the culprit is the latter

Tryed NB voltage at 1.30, 1.40, 1.55, 1.70, FSB term. voltage at 1.20, 1.40 (max), CPU PLL at auto and 1.5v, SB voltage at auto and 1.20v. No go.

very nice clocks. I hope to do 4.2+ on my 680i (was a piece of....).

[metro.cl]

that is som high volts on air, your chip is really sweet

While nice and appreciated, that isn't what I'd look for. 8hr P95 stability at least with good temps and 24/7 volts. 45nmm hates high voltage and hates high temps too, quick deaths and degradation. Plus 55C you won't pass much stability prroperly. BTW, you're using the outdated CPUZ.

[T_M]

CPU-Z 1.43 please

[lukas69]

Very nice cpu
i have one batch 740 but i think new batch are better

[barzi]

Bios 1006? Where did you get that from?
The newest bios i can see is 1002.

Has it gor rid of the vdrop bug? and the EIST bug?

Sorry, i've mistaken it, it's 1002

Thanks Lukas. They get very hot though

T_M: i'm not gonna go thru the tests again but got the newer CPU-Z

[SmokeyTheBandit]

Got an E8500 with the exact same batch (Q745A554)
I hope it will do about the same numbers as your super cpu !

[AriciU]

I bet it will! If you lay some 1.65v on it that is Maybe yours will go higher if you don't have mobo fsb wall @ 510.

1002 bios better suited over the 906 i use on my P5K-e /Wifi?

[AriciU]

Yes. With the 0906 bios there is no way in hell to get cpu voltages between 1.5 and 1.59v. I've posted a voltage list in the Asus P5K-E thread regarding what voltage you set in bios and what you actually get using 0906. You might want to check it out

[AriciU]

Ok. I found out what my problem was. Temperatures. My DVI cable managed to catch my eye somehow and i noticed that it was quite long. Here's what happened next....





Motherboard temperature in bios was 11C, CPU temp always stayed (idle) at 21C (i think that's a bug... it was 21C @ stock volts and mhz and 21C @ ~4900 and 1.68v). Outside temperature was 1C

Max clock or max FSB (i cannot disable EIST so i get 6x multi in CPUZ... it was set as 9.5x in bios as setfsb shows it though) @ 9.5 x 530.6 = 5040.6Mhz



09.484s Spi1M @ 9.5 x 516.2 = 4904.5Mhz

[giraffen]

Lol, you throw the case out of the door, that´s the way to do it
Btw. Nice clock

[George_o/c]

5GHz on what ?
A few posts before, I saw a 9.5 multi on a screenshot of yours ... What on earth happens ? ...

[AriciU]

I cannot disable EIST man. Multi auto goes to 6x while idle. I could not throw some orthos at it to send it back to 9.5x at those freq and manage to get a screenshot too... it would crash within miliseconds.

[AriciU]

Don't want to lose max overclocking potential by using it 24/7 at the rather high 1.48v so i'm gonna settle for this for 24/7. SS clocking coming tommorow hopefully

Nice1. We were about to put the SS on it and the dsmn thing would not start up after we installed fresh windoze and vapo Mobo is dead.
