To be precise : You can run it, but CPU test will crash/display error and your overall score will be always 0 points.

Other than that, you should be fine without SSE4 (if CPU ucodes were updated/programmed correctly).

shuck666 already gave me the link with kets moded OC Bios, i will update the bios next week!
Ok,U need sse4.1 for more things then running Time Spy. For Example, when Windows10 goes to install, it ck's the cpu,and ck's that sse4.1 is installed. If the cpu supports it,but DOESN'T have it, Windows 10 will usually fail to install. CPU'S such as P4's without sse4.1, WILL install Windows10 because the installer ck's the cpu & see it has sse3, doen't SUPPORT sse4.1, so doesn't ck for it. http://www.cpu-world.com/CPUs/Xeon/Intel-Xeon%20E5450%20-%20EU80574KJ080N%20-%20AT80574KJ080N%20%28BX80574E5450A%29.html

If the cpu codes had been updated correctly,sse4.1 would be AVAILABLE. That's the easiest way to ck if the code was added/proper code being used. See pic for example of what e5450 should look like in cpu-z @ idle---> http://cdn.overclock.net/5/5b/5b4e9616_Screenshot_8.jpeg

yes, SSE4.1 and vt-x are missing i will update the bios next week!

I think Win 10 fails the install (on CPU with software "turned off" SSE4.1), because CPU's ucodes are bad.

You are right, and I forgot, SSE4.1 support can also tell if ucodes were added correcly.

This is a nightmare wheee.gif
When everything seemed good, tried the Aida64 stress test, fail in 5 minutes. Prime95 was fine for 12 hours (and still wasn't any error, it was me who stopped it)
Narrowed down to the rams.
Checked one by one. Checked in pairs, checked the slots, no error. But when all the 4 modules are in the slots then Aida fails in 5 minutes.
Noticed that one pair is ver 1.1 at 4-4-4-12 2.1 volt , the other pair is ver 4.3 at 5-5-5-18 1.8 volt . but both have 1.8volt 5-5-5-18 profile so they were on it, manually as you can see in the previous screenshot.
I have a spare pair, those are ver 4.1 - other than that they're the same as the 4.3 version so i've replaced the 1.1 pairs with these.
Those 4 worked, no fail in Aida.
I thought that was it.
But The pc sometimes unable to restart, stuck at blank boot, even before bios. Sometimes the pc turns on when i switch the PSU to on - without the power switch of the chasis.
I tried various setting and upping the ram vcore from 1.8 to 1.9 seems to solve the boot/reboot/auto poweron issues.
I have set everything else back to where it was before, Aida is running, so far so good. 20 minutes passed. Fingers crossed.

And then it should go with CPU X5450 with 3GHZ 12MB cache?

Excuse my english is not so great frown.gif

Yes but these xeons need deep fine-tuning even at stock speed so you need a lot of patience to make it stable while still keeping it cool and not overvoltaged. I'm very close now but this is my 4th day..

The set of 2.1 volt rams seem to have been seriously undervolted. Alot of times when running 4 sticks of ram,they need to be over volted by .1 or .2 if being OC'd especially. U may also need to add a touch to the NB voltage.

The craziest thing about all this is I built and thoroughly tested near all the LGA771 Xeon's from slow to fast 3.16Ghz. On Fallout 4, it seems to much prefer the SSE 4a Opteron 1389.

On the X5460 the CPU would be taxed to 100% nearly all the time and ram was always out. I just tested Fallout 4 and the CPU hovers around 40% at 5k.

Not to mention now it feels like 60fps and runs better than my X5650x2 rig on this game. It is smoother even on PCIe 1.0.

This screenshot is on old drivers with GPU Max temp set to 67C limiting clocks. Now I'm on 17.4.1 with 80C max temp on RX 480. Couldn't see OSD in game for some reason but it's running 4x faster now.

No they weren't, as the 2.1v profile is for the CL4 timing, there is a CL5 profile with 1.8 volts (checked in Cpu-Z).
As for the NB do you mean another touch? It's already on 1.2 (1.1 is the standard). Btw the ram is not OC-ed but the CPU.

If you already bumped it 1,wait & see if the ram being @ 1.9 solves the issue.
