Tested it with 4.3GHz@1.32v, stabile, temps around 65c(tjmax 85 via realtemp).

For everone who asks about X vs E. Here are my measurments from the other day, using wattmeter and the same bios settings, only cpu switching!
(Setup on bench table, not in case, temperatures god about 5-8c higher in case, neither cpu was lapped at that time, neither was Prolimatech)





There is clear advantage for E series! But my E5450 vas bad, and x5460 could get higher and achive 4.0GHz @lower vcore. So my x5460 is beter than e5450. smile.gif

E series is far better! IF YOU GET GOOD E5450!

Yes, I also think E series is better when aiming at 4Ghz between the E5450, X5450, X5460.
But it is more expensive than a X5450 which will do 4Ghz.
Then again a E5430 is a big boy. Consider it is a Q9450 at less than half the price and a lot better to overclocking. wink.gif Cheaper even than a Q6600!
Then there are the L series Xeons that consume a lot less energy and they can be silent cooled. Still a lot faster than a Q6600...

After having a Q6600, E5440, L5420, E5450, X5450 I can say each one has its usage, even the slow and power hungry Q6600, it`s a direct fit...


But let me ask you a question.
Why do you run stress tests that have no meaning? Why on earth do you care if it is stable after 5 hours on something will never be run at any normal usage?
Personally I don`t waste so much time. I set a goal, to hit such Ghz. If I POST with the lowest Vcore I`m happy with (always aim for low Vcore) then I load windows. If it loads then it is a matter of some fine adjustments. Maybe set the Vcore a step or two more (or a little more than this), and then lower the FSB by 5 so to eliminate any possibility except of cpu there is northbridge/mem instability too, but this also adds stability to cpu also (lowering the FSB from the theoretically stable point) . Assuming I know the mem is 100% stable as I have already run memtest86+ for at least 10 cycles (it is the only test I run). This usually is 100% stable for any usage.
I run video editing -and multitasking- so playing with stability is an issue for me. Instead of just loosing a game I loose all my work, so I am not joking around stability.
But can`t run tests that have no point. Anyway, you can be more relaxed I think. And I can be more careful I could say. But anything that works for someone, I think. Just a thought... tongue.gif

Hello Everyone.
I just now joined so that I could post my success story.
I just upgraded a Foxconn G41MXE with an E5450 (E0 stepping SLBBM).
This required No Bios Modding, It works with the latest bios from Foxconn.
I'm seeing sse4.1 that I didn't see with the Pentium dual core it had before.

I put a Rosewill heat pipe (that I got off amazon for $14) to cool it down, but seriously, the thing didn't need it.
I tested it for 2 hours running prime 95 with a core 2 duo all aluminum stock heatsink and never got higher than 58c. With the Rosewill heat pipe she doesn't even kick on the fan unless I start gaming, since I told the bios to only start the fan after 40c. This Xeon is way cooler than the q6600 and blows it away at the same clock.

Just to try, I also tested an X5450 (C0 stepping SLASB), which worked too, but since the motherboard is only rated to 95 watts, I decided the 80 watt E5450 was the perfect match. I didn't see any point to risking the capacitors when the E5450 was available.

Thanks for all the info. You all and this page helped turn an old jalopy Pentium box into a worthy game machine again.

Her current stats:

Foxconn G41MXE
Intel Xeon E5450 @ 3ghz (Didn't get a chance to really test any overclock yet, but really stock speed is good to me smile.gif
GSkill Ripjaws 4gb DDR3 1066 x2 overclocked to 1333
Evga Geforce GTX 560 Ti

Her next upgrade will be an SSD. Only thing left to upgrade. Woohoo!!!

Now I've got to find a home for the X5450. :-)

Has anyone have intel Xeon 33x3 LGA771 series cpu datasheet? All i find is 3xxx series with LGA775.
I think that Yorkfield-CL architecture is just a Harpertown with disconnected few land contacts so it can't be used in dual-processor configurations. It would mean that we can try blocking those contacts on Xeons 5000 series and test them on unsupported chipsets like Q and X series.

Add another ASUS P5P43TD-PRO to the list. X5460 currently @ 3.8Ghz - working on tweaking it still - but running really smooth.
Thanks to Moondoggy for the BIOS - worked like a charm!

I have an MSI G41-P33 Combo. Does anybody have a modified BIOS for this board? Just got my E5430 in biggrin.gif.
post #2507 of 12376
Just a note to anyone who has a 790i based bored...

Tested on EVGA 790i Ultra Board...

The Xeon E5405 does NOT work. It will boot upon first install, but afterwards it will not POST and just gives an "AA" code on the LCD display. This problem was not solved.

The Xeon X5470 works! I tested it on EVGA P10, EVGA P09, and XFX P09 bios. A side note, the XFX P09 bios is the only one I got my 16GB of DDR3 RAM to work with.

Noob here ... I've got the GA-EP45T-USB3P too and am looking at the Zeon E5450 processor.

...@joemill453 ...can you share your experience thus far. Did you try that bios from buy1get4

...@buy1get4 ...mind sending me that file or posting it somewhere.

Thanks. Looks like I'm gonna learn 771 modding...

Been reading this thread and have performed the mod. I have an asrock g41c-gs with a x5450 E0 stepping. I am able to run it with no bios modding. The bios recognizes it. My problem is that I'm not seeing the ssse 4 or vt-x instructions. CPU z recognizes the cpu as a e5450 while windows sees a x5450. Also using 3dmark to compare results from my c2d it wont recognize the cpu to validate the score. Coretemp says its a x5450 and my cupid is a 0x1067A. Can someone please help?
post #2510 of 12376
Add Xeon microcodes to the bios, use a modded bios.
CPUz will still mention it is E5450 in the "name" section but in the specification section will mention it is an X5450
