They use regular DDR4, non ecc or reg.There are a total of 16 DIMM slots with support for NVDIMM (Non-Volatile Dual In-line Memory Module). Each processor is connected to 8 DIMMs and of course quad-channel memory support exists. Both RDIMM and LRDIMM modules are supported at speeds of DDR4 2133/1866 and 1600.
The ECC memory this board can support is generally meant for servers, where any data corruption is unacceptable. Since this isn't really a concern for most of our readers, we went with standard UDIMM modules from G.Skill, rather than equip the board with ECC memory.
Ideally we wanted to populate every DIMM slot with DDR4-2133 memory so we reached out to our good friends over at G.Skill. Happy to oblige, they served up 16 4GB sticks of Ripjaws V DDR4-2133 memory for a total capacity of 64GB, which will allow both Xeon E5-2630 v4 chips to enjoy quad-channel memory support.
G.Skill sells this memory in 16GB quad-channel memory kits for just $74 each, taking the total cost for this build to just shy of $300. For those wondering, the memory operates at CL 15-15-15-35 timings using 1.2 volts. The modules are available with either red or black heat spreaders and we went with red.
I bought 2658 v3 QS chips from the seller and it was good transaction (Current price is 299, but I paid 225 each). I have been reading this thread and decided to go QS or Retail CPU with few more dollars because I don't want to take too much risk (if there is any). QS is more close to production, but I don't think ES is. And it seems that the seller gives you 60 days warranty if it doesn't work.Guys, been reading this thread for a while now. Almost completed it. I started reading this thread while i debating if i should go with the ES model or not.
I bumped into this seller on ebay and he was extremely positive that the cpu is not the first engineering sample, and was close to production.
Intel Xeon E5-2630 V4 ES QHVK Remarked as SR12R 2.1GHz 10Core 25MB Processor CPU | eBay
He tells me "look at the HWiNFO64 test screenshot,the stepping shows L0.It means it's not old first ES version.
The old ES version is A0-A2.....So please don't worry."
However being wary about the strict non-return policy i didnt pay much heed to his claims.
So is it true that the QHVK is the first engineering sample, and not close to production? And if i need to get one of these it shud be QK3G
Anyone has had great success with any specific seller and model? please post the ebay link.
Looking at their reviews, it does look like a lot of people who brought the cpu say the cpu has been running stable.
Did you get them working ? What was the issue ? QHZD do work nicely for me 24/7.I need help. I bought a pair of E5-2698 v4 ES Broadwell-EP's from icomputer_parts_international on ebay. Some people here & elsewhere used with no complaints (and linked/listed their compatibility chart a couple times in this thread.)
These two CPU's simply will not boot on any motherboard or UEFI combo I have tried and I can't figure out why.
All motherboards tried do work (three are recent NIB purchases). I am using a brand new retail i7-5930k. a gtx-980 and a single stick of DDR-4 to flash the bios. (Nothing else installed)
I'm just lost as to what to do next. What am I missing? Thoughts?
Thanks for your replies. I agree the QS is a better option to go with.I bought 2658 v3 QS chips from the seller and it was good transaction (Current price is 299, but I paid 225 each).
