I guess source of confusion is coming from what I read on ebay, some sellers advertise their QS having model numbers starting with Q1xx but some publish actual pictures of units having model number in SRxxx format// ... sam55todd said: some things are ... //
Intel QS are identical with production units except with ES bit set to 1.
they have no warranty because they are free intel gifts(NDA) for qualified customers.
Qxxx is ES or QS. SRxxx is production unit,never QS. the chinese re-print the IHS to hide the original customer of the processor.I guess source of confusion is coming from what I read on ebay, some sellers advertise their QS having model numbers starting with Q1xx but some publish actual pictures of units having model number in SRxxx format
there is no unofficial BIOS 1.0 for this mobo, no way.I am getting Supermicro X12SPA-TF motherboard. Will I able to use one of the ES chips with this motherboard? Considering something cheap to play with:
typical issueHey everyone, thanks for all your help. I went on vacation for a little bit. Turns out it was a socket problem and I didn't screw the screws tight enough using my cooler.
I finally got around to build up the 8461V @Kizune sent me in August and seem to be in a situation where four (!) of my eight RDIMMs fail to POST on this X13SEI. Two throw "failed component" errors, one says "signal too marginal", and one "fails to train".
bought 2x DDR5 16GB used Hynix from ebay too(other seller) both came DOA with missing SMT components.I am beginning to suspect this eBay vendor MICRON 32GB 1Rx4 PC5-4800B DDR5 4800MHz ECC Server Memory (MTC20F1045S1RC48BA2) | eBay was less than scrupulous - I paid $40 a DIMM which is like 1/3 of street price and the 50% failure rate could be explained if the DIMMs he sent me were his customer returns
aha, spot on. three of the bad DIMMs were missing resistors (?) near the pins and the fourth had a decoupling capacitor ajar.bought 2x DDR5 16GB used Hynix from ebay too(other seller) both came DOA with missing SMT components.
you could check micron/hynix dataheets, they have mostly schematic and resistor values shown.anyone know what value the 0201 resistors near the edge connector should be or should I just ohm it out?
i don't see where it is located. another picture pls.thanks. do you know if the other end of the resistor is ground or the data line?
