[MOD] LGA775 Support For LGA771 Xeon CPUs - Page 1184

post #11831 of 12080
So I just built up this EVGA 790i Ultra SLI system with 8gb ram 2 different pairs of 1600 2gb module ram and e5450 on Arctic Cooling Freezer 7 Pro.

Booted up to bios at first but would freeze in the bios? Like set time and then move on and sudden freeze... Restart go back in and again a freeze... now long continuous beep upon start... Looking over the boot codes but this is like a fresh build, no overclocking or anything.

Thanks

Check motherboard compatibility with those ram sticks... 790i can be very picky...

C1 code here on 790i long continuous beep and no post... I think it's the Winbond chip, what is that thing anyway and model? Wires bridge... need good microscope to be for sure but I think they bridged possibly...

*update* clean memory slots with toothbrush and goof off, working again. Have to fiddle with module configuration though for it work. Start off 1 module slot 1 then proceed 1 module at a time.

Now on 4x modules I can't seem to boot at 3.5Ghz on E5450. It freezes. I added more voltage but still was unable to boot. It dislikes without vdroop voltage, so I stick with vdroop voltage.

Maybe it needs 2x modules max for overclocks? I had FSB at unlinked for 1556 (389 x 9) and DDR3-1000. Tried a lot of things. Maybe it's the 4x modules causing issues?

Now I found 1.200v is fine for stock and it indirectly lowered the Northbridge/ Southbridge temperatures.

Any advice would be helpful for 3.5Ghz (1556Mhz FSB). As for CPU vCore, CPU FSB voltage, PLL, memory, SPP, MCP, etc?

ddr3 775 mobos are very tricky. I recently discovered that my Asus P5QC refuses to run the divider i use in bios. if strap is 400, it will not appy the bios divider for 900 ish ddr3. At 1200 divider it won't boot, and in 1359mhz it will apply 3:5 fsb:dram so 755x2 1510ddr3 speed.

i would not run that mobo with more than 2 modules of ddr3. the CPU is not pulling you back . It's just the memory controller, as in any other 775 motherboard.

downclock as much as possible your ram speed, and go for it. PLL should be like 1,56-1,58, fsb at that low i would say 1,2v should do the trick, but try 1,3 to be sure. memory just stock, NB, RAM, SB and Pcie auto.

I remember that board was very tricky. One friend of mine had it, and it was really difficult to get it run with ddr3. Maybe you can try ddr2

Well I found that the only adjust needed for e5450 to 3.267Ghz needs only CPU FSB 1.175v to boot all others default 1st settings. Ram 1.5v.

I also noticed no performance decrease with HT to MCP multi from x1 to x5, and x1 is needed for overclocking.

For 3.3Ghz needs 1.65v Memory, will not put up with anything less. Also 1.175v CPU FSB is fine, only 1.25v vCore for e5450. I notice a near 50% increase in memory bandwidth from DDR3-968 I believe to DDR3-1467 on 8-8-8-20-2T 1.65v.

So I'm up to 3.3Ghz on 4 modules of 2GB 1600Mhz. Would not put up with 3.4Ghz no matter nearly anything I threw at it... Code C1 board. I could maybe boot with 2 modules though, never tested it. I once saw 30,000 points CPU Queen but can't remember settings... It wasn't stable system wise but took on tests fine... It's not the load that causes instability it's the basic things like restarting of all things... It often C1 codes memory upon restart and resets BIOS.

Most interesting of all this is The Opteron 1389 is outperforming the E5450 with DDR3-1467 on DDR2-800. The Opteron does over 10 1/2 GB/s on DDR2-800 and just about 375GB/s L1. The Xeon E5450 does 408GB/s L1 at 3.3Ghz but only 7-8 1/2 GB/s memory on DDR3-1467. At DDR3-968 or so is just 6 1/2 GB/s memory. So DDR3 helps the Xeon a lot just not as fast as the Opteron on DDR2-800.

Anyway this 790i E5450 system is running fine at 3.3Ghz DDR3-1467 for my friend. Everything seems to be doing great. It's 10% faster than stock E5450, but L1 goes up by just as much basically. From 370GB/s to 408GB/s from 3Ghz to 3.3Ghz. The Opteron does 370GB/s L1 and 10 1/2 GB/s stock at 2.9Ghz. So it's by no means any slower at all than any of these LGA 771 Xeon's.

*update* it crashed on intelburntest... Need to up all voltages 1 notch... Now I'm on vCore 1.275v i think haha, CPU FSB 1.175v, memory 1.65v, SPP, MCP up 1 notch like 1.37v/ 1.55v, and left CPU PLL 1.5v minimum... Seems it will pass 128 thread 10 tests Intelburntest now.

*update* System was found to be unstable haha.. more voltages.. i won't update about it anymore haha *headache* wink.gif update #2 haha PS - it was stable just ran out of ram on Win7 mini max 2gb so whatever its all good.

Have you tried 2T command rate ?

I dialed it back to stock 3Ghz... too many issues. Now at 1600mhz ram 9-9-9-24-2t-7.8ns 2.00v of all things?!? I could try 1.65v but have not tried it.

Now on AIDA64 I see a sensor on the Winbond hovering around 90-92C... any word on this? I think it's an error. That was the issue before is this chip.

Thanks

DUDE! 1.65 voltage ram is the minimum that really runs stable on the 790i chipset. Soooo,posting about how it crashed with lower voltages and the amd was just as stable is starting to get trollish. rolleyes.gif All the info for that board & recomended memory is mostly available throughout Laithan's thread. Most people end up needing @ least 1.8v when using 4 sticks with those chipsets,unless they have the 2.0v ram.

Right on. It's working fine. There is a sensor on the Winbond reporting from AIDA 90-92C. I think it's incorrect?

I could get the system stable at 3.3Ghz and pass Intelburntest, yet would reset bios after restart and such stuff. I even turned up the voltages and it didn't fix it. I apologize for the perceived trolling. I'm only just sort-of reviewing them both. Since no one ever owned an Opteron 1389 and never ever received not one bit of publicity. It's a rare Gem not many are aware of.
