Need help on ASUS DSEB-DG

[bearcatrp]

Kind of figured. Had to make sure though. Tnks

Great, now show us those E5420's at FSB 400

[bearcatrp]

I did the mod. Looked inside the bios and it's recognizing my 800 MHz memory. Do I still need to do set FSB to 800 in ubuntu? Also, I enabled speed step. Looking at my CPU settings, I can change it to any of the following, 2ghz, 3.67ghz, 5.33 ghz, 7ghz, 8.67ghz, 10.33 ghz, 12ghz, 13.67ghz, 15.33 ghz, 17 ghz, 18.67 ghz or 23.67 ghz. WTF! Will max them out but obviously this is wrong. Any way to correct this to show proper ghz?

I disabled speed step and it's locked at 2.93ghz. Not sure if ubuntu is ready this right. Any other way to verify what the processor is actually running at?

Another question for the pro's, do you folks do a 1 week burn in after applying arctic silver? Read this is required to throttle at different speeds before running 24/7. Have always done this but thought I would ask.

I stopped using AS5 when I discovered Diamond7..
I put it on,fire it up and CRUNCH!

If you have to use AS5, you need to give it some cycles for it to cure. So, crunch for a while, then shut down the PC and let it get to room temperature. Repeat X times and see if temps become reasonable.

I'd ditch it and go for IC Diamond, as Movieman mentioned

Thanks for the info. Will have to order some. BTW, do I still need to set FSB even though the ram is recognized as 800 in the bios? Ubuntu is reading the xeons weird since doing the BSEL mod (see above post) so not sure how to figure this. Works though. Shaves off about 10 minutes crunching on HDC.

[jcool]

Just check in Bios whether the CPUs are running at FSB400 (might also show 1600). If your ram speed is 800Mhz, than's a good indication it does really run at that speed.
You do not need SetFSB or similar, this is a pure HW mod. You can, however, OC past FSB400 using SetFSB. You would need to run Windows for SetFSB to work though.

[bearcatrp]

Thanks for the help. Any reason why my CPU speed is showing 2.9ghz instead of 2.5? If this is correct, I don't mind, just curious.

Crazy old thread yeah i'm never one to hop on fresh threads... just joking.

Anyway apparently your chips were 1333 so take 2500 divided by 333 and u get ur multi of 7.5. So the mod was to from what I believe to switch in hardware from 1333 to 1600 which forces fsb from 333 to 400, so 400 times 7.5 equals 3000mhz. For some reason it's reporting a bit less which is totally normal. Tweak around with Spread spectrum to get the reading to be at 3Ghz. I think enable/disable fixes it if u have it.

Good luck ----- PS ----- Also curious if any of u guy's still rocking these 771 systems?

You betcha. Someone donated a dual socket LGA 771 system with a ASUS DSEG mobo to me 3 weeks ago. Also had some Dell 2950's and two ML370 g5's. They are still good crunchers, especially if you use Linux as the OS.

[bearcatrp]

I sold mine years ago. Rocking a dual Westmere system now. Trying to win the lottery to build a dual 12 core system to keep up with MM.

[yojimbo197]

Does anyone still have the CD that comes with this motherboard? I need to update the BIOS so it will recognize the microcode on the two E5450's I want to use in it. I've tried to load the BIOS via DOS on a USB stick along with the AFUDOS utlity, but it didn't work.

After choosing OS, pick what you need.

Yes i have already been here and picked up the bios file, afudos, and the manual. unfortunately the manual says something about inserting a cd that came with the mobo when trying to install a bios update from a usb drive.

[bearcatrp]

Have you tried the flash bios utility under bios utilities? Otherwise you might have to contact asus to see if they could help you with a copy of the cd.

Yep, the flash bios utility is called AFUDOS. Tried it already without the disc on a bootable usb drive.

Well I managed to update the BIOS. Turns out the instructions were misleading and/or wrong. Unfortunately, my E5450's are still underclocked to 2 .0Ghz and now I only have two cores running instead of 8. I suppose its time to ring up ASUS.

[bearcatrp]

You verified in the bios to use all cores? Been awhile since I had mine so foggy on the issues I had to get them running.

Well thats one issue that i can check. the bigger problem is that the chips seem to be downclocked. and linux mint says they are pentiums.

[yojimbo197]

Yeah so it turns out that there was an additional BIOS update that was on only the business side web page on ASUS and not the other ASUS page for the mobo. Very confusing. I updated to the latest 1009 BIOS, and then reset the defaults. Ouila, 8 cores at 3.0Ghz, and Linux sees the chips as E5450's. Phew. Now its time to catch up on points..............

[bearcatrp]

Nice job. Not the most energy efficient but solid crunchers.

I managed to get a good deal on the E5450's by harvesting them from a HP blade server i won in an auction on eBay, along with 24Gb of RAM. I sold the RAM off and now just have an empty blade server hull and the E5450's. Right now I'm just testing these E5450's out before I put them in a PowerEdge 2950 g3 unit for refurbishment along with 32Gb of ECC RAM and two 15K 146Gb SAS drives.

Power is an issue only because our AC unit is a major electricity hog and that outlet is on the same circuit as the washer and dryer downstairs. Long term though, I"m hoping to shrink my "patch" down to 2-3 computers total with one build a dualie with SB or IB multicore chips. However, this isn't going to happen right away, as I need to sell off my MacPro, the ASUS server/workstation, and at least one other computer. I have a buyer lined up for the ASUS server/workstation, but I am not sure how long it will take to sell the MacPro or one of the other computers. Plus I hate giving up cores. it's either that or find a hosting company that gets a good deal on electricity. Unless I win the PowerBall. Then I'm building that 4 socket Puget Sound monstrosity and taking some serious pie.

[bearcatrp]

The mac pro should go fast. I had 2 of them before selling them off. The 2008 mac pro was nice but when apple updated after that, I had enough of paying the apple tax. Building my own ever sense. Trying to sell my westmere system now (mobo with everything) to finance a xeon 10 core. Dam expensive. Looked at AMD latest 16 core in a 4P setup but not sure I want to use AMD. Glad to hear its up and running.
