1366 X58 Xeon 5650

Can only get to boot properly if i leave it at default settings, if i try booting just a bit over stock speed i keep getting these weird start up errors..

Boot block compatible ver 0.84.. etc.. bad bios checksum, then if i reboot again i get overclock failed and need to set it back to defaults.

No they wont be all loaded at 22x, ive set to 20x and raised the bclk. My board is quite happy going above 200.

Its an asus rampage 2, cracking mobo

mm, Cinebench R15 191x22 (4202) = 937, 210x20 (4200) = 939, seems 22 multiplier is working :confused: (didnt think my mobo would get that high, granted not that stable, but stable enough... just)
 
I'm still having a tricky time with my X5675 and the rest of my setup.

I'm a novice Overclocker, which doesn't help, but I just can't figure out how to get my RAM running at its 1600Mhz stock speed.

As suggested by tribz, I've tried upping the DRAM Bus Voltage along with various other settings (CPU PLL, QPI and DRAM core etc) but can't make any progress. Whenever I set the DRAM speed to 1600Mhz and the UCLK to 3200Mhz my machine does not boot. I get a blank screen and then when I reboot it say "Overclock failed".

The timings on my memory at 1333Mhz are not very good either (9-9-9-24-107-2T).

If anyone is running 24Gb of RAM with a Xeon CPU on a ASUS P6X58D-E motherboard and can share their setting or offer any advice that would be great.

Once I've got the RAM running I'd like to push up the CPU speed. I'm hoping I can get around ~4Ghz with my air cooling using a low BLCK thanks to the 25x multi I can use on the X5675. Not sure if anyone has any thoughts on how feasible that should be?

When you get that message, try a reset with ctrl alt del or the reset button and see if it then boots with your overclock. My Asus board was doing this, I had to do a double boot to get going. It's stopped doing it now and I'm not entirely sure why.
 
I don't know about X58 but I've had several boards from earlier generations which struggled running RAM at the rated speed if all the slots were filled (I'm not entirely sure why). If you run 12gb or 18gb do you get the same issue?
 
Been having a play with this X5650 tonight and have it stable at 4.18Ghz 190bclk. I previously had my 950 at 4.2Ghz 200bclk and feel this chip wants to do more. I am on custom water and the temps are so much better than my 950. But I am being held back with the rather annoying bug on my EX58-UD5 that limits the uncore multi to 20X.

If I change it one notch then it fails to post and constantly flashes a C1 error code until I clear the CMOS. I've tried enabling/disabling turbo and C1 states but it seems this is just a limitation of the bios. I am using the latest F13j. I did some searching and they have fixed this with an update on the UD7 but not my board it seems. If anyone knows of a newer beta that fixes this then give me a shout.

For now I have the uncore at 20X multi and my ram at 10X using Teamgroup LV PC2133Mhz dimms. I have the timings at 9-11-11-28 and could probably tighten those up a bit. I have had to give it 1.375v on the QPI to keep it stable at 3800Mhz uncore. I am tempted to see if I can push this further but am concerned about degrading my chip. How high should I be able to push the uncore safely? If I push the QPI volts a little more then I may just be able to get it to 4.4Ghz.

Overall I am pretty satisfied to have similar single thread performance to what I had before and the extra cores. Well worth the £70 I paid for it on ebay and now I have some extra cash to spend on upgrading my GPU :)

First post here after years of reading but never joining up!

I decided to get an X5650 to have a play around with in my old Asus P6X58D-E. It turns out that this chip is actually a pretty good one (for once I won the silicon lottery!). It started straight up at 4.0GHz at 1.18v and ran Prime95 no problem. I then tried 4.4GHz and it got into Windows at 1.2v.

I can also confirm that x22 multiplier works on all cores on the P6X58D-E:

2hx269.png


So far I've settled at a stable 4400MHz (22x200MHz) at 1.37v. HT is on and RAM is at 1600MHz triple channel 8-8-8-24-1T. I ran prime95 for an hour before I stopped it and it encodes faster than my 4770K at 4.5GHz. The ironic thing is, if these chips had been available for this price a year ago (£69 from an auction site) then I wouldn't have upgraded to haswell.

One thing to note is that mine wouldn't post at 133MHz BClk with the DDR3-1600 divider. It'll run happily at 220MHz Bclk on this board, just like my previous i7 930 used to (225MHz in fact). Very impressed overall!

Is it worth trying for 4.5GHz do you think? It might just do it stable at 1.40v-1.42v but temps are higher than Id like as Im just running a megahalems RevB with a very quiet Sythe fan. I may have to get an SSD for this thing and use it as an encoding PC, at the moment its using a WD Raptor that's 11 years old and still going strong!

Not sure if its similar, but as mentioned above, my Asus P6X58D-E would not post at 133MHz Bclk with 1600MHz RAM / 3200MHz UCLK.

Have you tried 200MHz with the 1600/3200 divider? That works fine for me.
 
dam... i have been keeping an eye on these for a while, now with this thread the price is likely to increase :-) the 1366 boards are already holding their price well.
I was hoping the new haswell-e will lower the price a little more too.

But seriously i have been looking at daul x5650's in the dell t5500 or t7500
Unfortunately i don't think the dell boards can be overclocked, but at £500 for 2 x 6 cores (24 threads) and 12/24 gb ram this has got to be the bargain of the "moment" i think.
I have even missed a few on bidding at around £250 :-(

(i feel a bit bad selling out for the Dell (as it is an ugly case), but at this price i am very tempted)
the t7500 has a 1000/1100watt power supply and 3-4 x PCIe slots (may need some 8pin adaptors or a newer PSU though)

what do others think of these dual CPU Dell's for the price?
 
Not worth it. You could build a superior custom build from used parts for that price. As it is my setup:

Xeon X5650 6 core w' Zalman CNPS9900
Asus ROG Rampage II Extreme
12GB (6x 2GB) Corsair XMS3 1600MHz
GTX480 1.5GB
CM Silent Pro M 850W
Intel 330 120GB
Seagate Barracuda 7200.12 2TB
Fractal Define XL

Cost me £265 ish.

But alas, it is not working currently. (it does currently have 6GB and a 460 in it as I'm waiting for parts still though)

*EDIT* Sorry, read as £500. If they are £250 then go for it!

Dell workstations use proprietary power connectors for CPU and board power though, so you won't be able to put in your own PSU.

that's great at £256ish
The buy it now ones are doing £500 with dual X5650 and 24GB ram
But a few on auction/buy in now do £250/£300 but only with dual quad cores (unless you are lucky). But this could be upgraded to dual X5650's for less than £100 so a total of £350/£400 + 2 x quad cores to sell (around £50)

I dont really game, just like a machine with a bit of poke to it and at bargain price (and option to game if i want)
 
whats the deal with x20 with turbo boost = x22 some people saying it runs all core at max speed others say they dont can any one clear this up ha as mine sweet spots @3.9 and i would love to get more with boost would hit me round @4.3

I have a Dell Precision with the dual quad cores. Unless I am mistaken they are all socket 771 (Core 2 Quad era Xeons) and have 667MHz ECC DDR2.

I think you are mistaken (but the dual 771 are still nice i feel for the current price).
Sounds like you have the T5400 which is a 771 (up to) dual Quad Core.
The T5500 (and T7500) are (up to) dual Hex core Xeons on 1366.
Then there is as the T5600 (up to) Dual E5-xxxx Xeons on i assume 2011
