Xeon 3050 OC'd to 3.2ghz from 2.13 at 1.2500 Volts???

[MikeDVB]

Am I crazy?

I upped my FSB to 400 and my multi is 8, so 3200mhz, I'm still at 1.2500 volts and I've been running orthos for the last 4 hours and not a single problem - temp is topped out at 45c full load for 4 hours.

I also ran CPU-Burn in for about an hour and had no errors...

Are there any other tests I should run or a certain configuration of a test (such as orthos) to make triple sure?

looks like you have a gem of a chip there! i want 4 ghz tommorrow ok!:beer:

whats the default VID of the chip 1.25? my e6600 has a default VID of 1.325 and i can do 3.0ghz todally stable at 1.25v

[Phrenetical]

screenies!

typically run dual instances of prime 95 on the maximum torture test.
:mad:

[nd4spdbh2]

orthos is multithreded and does a damn good job of finding out if ur system is stable or not quite early... IMO if you can do 8hrs of orthos ur gonna be pretty stable... 24hrs ur rock solid.

[MikeDVB]

Default voltage is 1.2250, I upped it to 1.2500 because at 1.2250 I failed orthos after about a minute =)

i'll drink to that

Here are some screenshots.

I just linked to them so that if you don't want to look at the pics, you aren't killing my server's bandwidth =)

Below in another response is a picture embedded into the post showing more information.

if you have 1.25v set in bios, droop under load is totally normal. you got a nice chip there. ;) lets see what it can do ;)

[MikeDVB]

I love Xeon 3050! =)

[(Clanger)(DOA)]

nice clocks great VID on that chip. What kinda cooling?

[MikeDVB]

Thermalright Ultra120 with a Panaflo 120x38mm Ultra Flow fan.

Bah I just noticed when I took the pic it had fluctuated up to 47c! Anywho on the stock Intel cooler I was getting up to 49~50c at full load at 2.13ghz!!!!

[(Clanger)(DOA)]

wow, thats not too bad. I think there is alot left in that chip. not too certain about that mobo. But hey lets see some higher clocks and some superpi's

[MikeDVB]

With what it came volted at outta the box, and what it's running right now I'd say it has a lot left to go. I agree that the board would probably be my limiting factor.

The long story is:

I was building a new system because I was getting tired of my old one taking 20 seconds to switch programs and stuff like that, I wanted to upgrade video cards and I saw no reason to go AGP when PCI is available and relatively cheap.

I went KN9 Ultra mobo with AMD Athlon64 x2 3800+ at 2.0ghz with 2gig OCZ ram and a Radeon x1950 Pro.

This system was what I would call "disappointing" for how much I paid and how much it didn't want to perform. On top of that the onboard raid would not work with my two 500gig Maxtor Drives :( I was going to RMA the board and Greenmaji talked me into going ahead and getting a Xeon 3050 and AB9 Pro.

The system started out to be a "Budget" system that is better than what I had (which is about 3 years old and wasn't top of the line when I built it.) I ended up upgrading the ram to Crucial 800mhz DDR2 4-4-4-12 for about $50 more because my OCZ could not actually run at 400mhz like it was supposed to. The Xeon was about $100 more than I paid for the AMD x2 and the motherboard was about $40 more if I remember correctly.

Basically I'm totally content with 2.13ghz - and even moreso 3.2ghz =) I will push the system and see how far it will go but I'm going to give the system a few days to break in the AS5 and for me to get everything set how I want =)

Even if I could get 4ghz I'd probably still come back to 3.2ghz because my CPU fan is really quiet keeping these temps at 45 full load!

Anyhow I'll update the thread when I push it to the limits!

Who me? :eek:

:p

Looking good Mike ;)

How's that raid treating you ;)

[MikeDVB]

Raid's nice, not quite as fast as I'd hoped but faster than the raid on my old system by far! =)

Mike

Looks like some of those initial problems you had to work through made it worthwhile.

[MikeDVB]

Yeah I got rid of the junk ram!

Did I mention I love this Ultra-120 cooler? Processor is at 23c unloaded =)

as read by what program? coretemp/tat?

what are your ambient temps? i find 23c hard to believe, even if ambient temps are 15c.

[greenmaji]

Yea. is that Uguru or TAT/Coretemp (not that Uguru isn't a valid number, TAT/Coretemp levels the playing feild for compairson to other systems)
btw.. HBB.. look up, delta 2C (making Coretemp ~25C or so)
Looks like with the low VcoreUsed and VID the heatload is low.

Using the Vdroop Vcore load, I'm getting 93.71 Watts heat load.. the low temps sound possible @ 20C (around 70F) or so ambaint.

nice chip

nice sig also with the pics of the hardware, hows that mobo treating you?

[MikeDVB]

So far I'm loving it for the price =)

The layout is a bit funky, EIDE connector on the board between the PCI slots which is a PITA.

Other than that it's been great, we're going to see what kind of FSB I can push. I only had to up the northbridge voltage .05 volts to get a 400fsb so I'm sure I can probably do more with it. We'll see here in a few days (probably next tuesday when I am off of work).

Greenmaji - I use Coretemp for my temperatures, uguru is usually within 1c of coretemp, but I prefer being able to see the temps of the individual cores.

I've figured out how to systematically overclock (this is my first "real" overclock) so it doesn't take too long to see what the limits are - I haven't pushed the limits of any of my components yet because this is where I plan on sitting for normal use (at least for now) and I knew my components were fully capable of this =)

And thanks for the compliment on the sig, it took me a few minutes to get that together =)

Ambient air temps when the chip was reading 23c on both cores at idle was about 19c. I keep my place chilled because I'm warm natured.

I also have a 120mm high flow fan on the back, and a 120mm high flow fan on the front, a 120mm fan in my PSU and a 120mm fan on my CPU heatsink... So I've got plenty of CFM to keep this monster cool.

I'll be considering going to water cooling in a few months to bring the decibels down but for now it's not any louder than my old system =)

Just because- wat does your superpi look like so far?
