1366 X58 Xeon 5650

I'll give it another go later.

Makes no sense that I was able to run the 920 at 3.8 but the 5650 won't go a touch above stock? :(

Edit - I also added an extra 6GB of memory to fill all the slots, could this be a cause?


Let's say you overclocked your 920 by 30%. That's probably not accurate but let's just use 30% as a number. You then add a CPU that's basically got 33% more cores than the 920. As such your VRMs could be at their limit.

There is no cooling on the VRMs on your board....

I could be wrong and it could probably be that you are using more RAM in there (as I know that can affect overclocking) but either way once your VRMs get to a certain temperature they will either throttle or simply burst into flames (and on some MSI boards it't the latter).
 
As the VRMs have no cooling, is it worth adding an after market cooling solution? I've noticed there are holes present either side of the VRM area where MSI place the heatsinks on their higher end models, they've obviously kept the holes but dropped the heatsink for the x58m.

Is there anything available? Or is it even worth doing?
 
Tried removing the newer ram sticks, no dice, still won't do anything more than stock speeds. Bugger.

Looks like I'll be waiting until Christmas to invest in a new cpu/motherboard bundle! My saving grace is that I can make back pretty much what I spent on it. Acquired the board 2 years ago second hand through an auction for £80 and have seen them go recently for more than that.

Are you trying to run your RAM at 1600MHz? If so try a lower divider.

At stock BClk I couldn't run at DDR1600 on my Asus P6X58D-E. Its not a limit on the RAM speed as it'll run DDR1600 fine at 200MHz BClk, just the divider doesn't work on the Xeon like it did on the i7.

So downclock the ram? I'll give it a go!
 
maybe ur xeon problem not mobo

if you tested it with everything no change then replace xeon

not logical mobo can't raise clock. worst mobo can raise clock at least .20Ghz

Anyone using 8GB RAM modules? It seems people here are sticking to 4GB ones. Also, the Xeon 5650 supports almost 300GB RAM. Any reports of desktop motherboards imposing on this large RAM support despite the controller being CPU-bound?
 
Yes, I've got one ex58-ud5 rig running 3x8GB and another running 6x4GB. Both running happy, although only mild overclocks as my cases are rather toasty.
 
Just bought another 5650 off the MM, so we shall see if its the chip!

Hope you get a good clock out of it. They're pretty amazing chips all told.

Still well impressed with mine, considering the cost.

I hope it is just the chip. Judging by your sig, I'm hoping to get close to a 4.4GHz as I too have the Triton. :D

If the new chip has no joy, then I'll get by on my old 920 and just make the jump to Skylake come Christmas. Still, I'm hoping that I can make the £55 upgrade in a Xeon work rather than several hundred more for new kit!
 
I will be interested to see if it is the chip, my gut feeling is it is the board as from memory it was a real bargain basement affair at the time.

That said a hex at stock speeds is still a super lovely thing, mine has been at stock the last couple of months due to problem solving a GPU fault, too lazy to change it back :o
 
I did a bunch of transcoding at the weekend so I can take some films on holiday this week. It's the first time I've really used my Xeon to its potential - having 12 (logical) cores at 4 GHz is pretty useful for that! It took about an hour to transcode a BD rip of a film to 720p @ RF24 I think.
 
Anyone think of a reason why i get lower benches at 20x200 vs 14x200? We're talking of a 50 point Cinebench difference, even after multiple runs. Thief and 3dmark were the same, lower performance as the multiplier goes up.

I'm not going above 65C at load so doesn't appear to be throttling.

Confusing the hell out of me!

it is not stable or high temp

That's the strange thing. my BLCK isn't changing, only the CPU multi and my QPI and uncore ratios are locked. There for qpil lin, uncore and ram freq are constant for each bench.

Thinking it might be a stability thing as 3dmark is giving me a timing error at anything less than x20. (The fact that i would be less stable at a lower freq doesn't make a great deal of sense to me but the fact that 4ghz gives no error but the lowest score kind of does)

did you test stability under prime95 or any programs ? test should be at least for 8 hours or 24 hours for the best stability
