Re: Help With Asus Z10PC-D8

My plan was to simply meld a power strip with a 220V plug, and paint danger warnings all over it. Point taken about surge protection, though. Honestly to be safe (well, less dangerous :lol: ), an integrated circuit breaker should be included that has a more appropriate amperage rating. For instance,...

Re: Help With Asus Z10PC-D8

It was anticipated that there would be an efficiency regression going to the higher clock speed. I will need to re-shuffle the positions of my computers since for a while now I have had access to a second circuit. That, or cobble together a way of supplying 220V since there is a 220V outlet near a c...

Re: Help With Asus Z10PC-D8

I'm certain they will put out more. 4 more threads per CPU, and an additional 400MHz at full load, and a reported ~5% IPC uplift. At this point I would be comparing between two different systems, but I would be happy to do some checking, especially if you can think of something quick and dirty that ...

Re: Help With Asus Z10PC-D8

Is it possible your PSU is the problem? I see you have both 8 pin connectors plugged into the MB so that's good. I see in the manual on p 2-18 that it won't post if there's not enough power. I know this is a stretch but I can't think of anything else to try. E5-2690V4 is 135 W TDP E5-2680V3 is 120 ...

Re: Help With Asus Z10PC-D8

I did inspect the sockets again with more emphasis on CPU 1, they looked great. Updated to a newer BIOS. Nothing helped. BUT, they work in my X10DRL with the one bad channel. So they are humming away now, but with less than 1GB per thread which I don't like. I think I am probably done spending a lot...

Re: Low power video card

I haven't measured low power GPUs. The assumption might be to buy a card with the smallest (newest) process, and the smallest heat sink. I think there are a few out there that will run passive, that would indicate low power consumption.

Re: Help With Asus Z10PC-D8

I haven't. It didn't occur to me that RAM might be a problem, since it runs with either CPU in one socket fully populated with RAM. It's a head scratcher for me.

Re: Help With Asus Z10PC-D8

They aren't ES, and the BIOS correctly reported the CPU type.

I didn't want to jump to the very latest BIOS, but the one I used is listed as supporting the 2690v4. I figured that an older BIOS had less chance of having performance robbing exploit mitigations.

Help With Asus Z10PC-D8

Hey guys, I have an ASUS Z10PC-D8 that I've tried to upgrade from Xeon E5-2678v3 to E5-2690v4, with limited success. Here's a list of the steps I took and what happened. Start with running system with 2x 2678v3 installed. All 8 RAM slots populated, 64GB. Both EPS 8-pin connecters used. 800W Corsair ...

Re: Used CPU Discussion

In my usual un-scientific and impulsive way, I found a pair of E5-2690 v4 CPUs for $450. I should be able to get about $150 for the pair of E5-2678 v3's, so this is a ~$300 experiment. I will get slightly better IPC, 300 MHz more speed at full load, 8 more threads, and possibly lower power consumpti...

Re: Used CPU Discussion

Yes, in fact on the dual socket Xeons I leave a minimum of 2 logical cores for the GPU, sometimes more depending on the project. At other times it does not seem to matter how few cores I try to use for a CPU project, the GPU is impacted unless CPU computing is suspended. It's not always like that, a...
