Will Registered ECC memory work on ASUS P6T and Xeon X5650?

[OW1TY2]

I'm currently holding these stuffs: P6T, Xeon X5650, 2x8GB DDR3 Registered ECC, GTX680 and a 600W PSU. I've heard that Registered ECC is not available on P6T, is that true? If yes, are there any bios (including non-official modified bios) that can make the P6T to support registered ECC?

I dont think registered ecc works on x58, but unregistered can, im guessing youd like to save money by buying ecc though you can just go sort by lowest and find the cheapest 4/8gb stick you can find locally, good rams are not neccesary since you can run 224 bclk (120pcie) while keeping rams at ~1333 so no issues going for slow ram, you may also wanna look at unregistered ecc and see if you can find em for any cheaper than normal rams, with asus board the ecc can function but ecc unregistered will work on any board though ecc may not be enabled depending on board

 

Heres some potentially useful sidenotes for ocing and for the board to get the most out of x58

Spoiler

Asus bios suck ass cause bios crippling so i suggest crossflashing to p6x58d premium for better overclocking ability via cheap usb bios programmer like ch341a, bios chip is located below sb near the bottom left corner, may be covered with a warranty void sticker (who gives a sht when its been like 12 years)

 

 

On the overclocking and voltages side

Bclk is best kept 200 and above since x58 gets a peerformance benifit with high bclk, though above a certain bclk like 220 youll have to raise pcie freq to 112, though i personally raise to 120 since its stable for all i know

 

Uncore is best kept ~3700-3900 at 1.4-1.45v qpi aka vtt, i have not degraded my x5660 even at 1.55v qpi for stressing my generic samsung rev f to 2200 8-11-10-20 2.46v so no those degradation claims are garbage and even if you do these cpus are dirt cheap anyways, though above 1.45v i dont reccomend for daily

 

Qpi freq just set it to the lowest that isnt slowmode, asus board is meh anyways so even at 224 bclk you wont be hitting a qpi wall, and they dont go higher than that cause then they run like snails

 

Ioh core can be kept 1.3v, thatll work for any oc in the 200-224bclk range, no reason to go higher but max safe ~1.6v since its 65nm if you are wondering

 

The ddr3 voltage 1.65v warning is garbage, same goes for the 0.5v rule, i run my samsung rev f to 2.46v at 1.48v qpi and no degradation or instadeath of the imc/rams, even for ~8 hours stressing prime95 large ffts (stupidly unrealistic workload that stresses the balls off your components) still no degradation. Though beware of volts over 2v cause not all rams can handle that it just so happens this garbage generic ic can handle and scale that far, personally i  say 2v is safe but others say 1.8v, though you prob dont need to care about this as again x58 doesnt need fast ram to oc bclk high, and higher ram speed performance can be noticable but most of the time negligable other than 2v+ overclocks aka not for daily, have a look at the Extremesystems ddr3 ic thread for more info on ram ics you should be looking for if you may be interested in ram oc shenanigans. X58 usually wont go over 2200mhz so aim for tight timing ics at 2000-2200mhz

 

For concerns on degradation these old platforms are bulletproof and take abuse well, even reward you for it, even if you do somehow degrade something cpus are dirt cheap same for ram

well that's a pity...I thought Registered ECC rams are available since I'm using Xeon X5650,now 20 bucks are wasted and I've got to go for the 40 bucks rams, dang.

You can just try them on your board and see if it works if you already have the rams, no harm in trying the rams, if it dont work it wont boot obv

If the sticks are 2Rx8 then they might work, but more likely they are 2Rx4 which don't work.
