my IMC is bad :(, i hope the new CPU will be better...
My memory controller on this 148 Opty does not work the same as my 146 Opty, i had higher oc on the 146 @ 277 1:1 and the 148 is only @ 267 1:1 same ram, so it has alot to do with the CPU you have, every one is different as im seeing with my setups and volts on the cpu and cooling play a BIG Part in what your out come is going to be too.:eek:
Tony, thanks for that answer. I acknowledge up front that you have probably forgotten more about memory than I will ever know in the first place so do not take this as a challenge, just trying to clarify what you said and looking for correction if I have it wrong.Quote:

I really don't want to put words in your mouth, but that's what I took away from your statements. Please correct me if I have it wrong. I think the problem is people see reviews like Anandtech's (FX-57/DFI/Powerstream) and look for 265-275. In a way you are victims of your own success, people are just used to seeing OCZ stuff clock like mad and perhaps do not fully appreciate the difference 2x1GB vs 2x512MB makes to the memory controller.
All that said I am still waiting for Newegg to get these back in stock. Back on the 9th you hinted they would be back in stock everywhere shortly, can you confirm or clarify that?
well
i will change my 3700 SD cabge 1205 spmw for an opteron 146 cabye 0540
lets see if my SD has a dodgy mem controler:slapass: ....and if i can have best results with this stuff...or do i need an FX to clear all the doubts...?:D
;)
I had an FX-55 before with a golden memorycontroller and the EB would run 3D at 280. I got rid of that and got a few other cpus's, but 270 is the limit now with the same bios, boards, voltage and settings.
The cpu acts totally different with 2GB of load than it does with 1024 or 512 load. It's just as simple as that.
The way i see it, older San Diegos and Winchesters had the best memorycontrollers, but had slightly less bandwidth clock for clock with the newer cpu's.

that being said, this is still kick ass memory imo, even if its WAY overpriced.
Yes it is Pricey, But i love mine and have no trouble with 3D apps and gaming ;)
I hope OCZ can produce these babies again in their former glory beta samples of mine - plucked back in my favourite opteron dual core loving 2GB OCZ PC4000EB for some blend dual prime95 actionQuote:

so far so good :)
Already know cpu is good for smallFFTs
http://www.fileshosts.com/DFI/NF4_SL...0cpu1_0_tn.jpg
max 32m = 282mhz 3-3-2-5 at 2.64v
max 3dmark /game = 278mhz 3-3-2-5 at 2.64v
On following cpus
- Opteron 146 CABYE 0540FPBW
- Opteron 146 CAB2E 0540FPMW
- Opteron 170 CCBWE 0544XPMW & 0546XPMW
- Opteron 170 CCBWE 0546SPMW
these aren't even the best i've seen a few retail pairs in OZ doing 285mhz 3-3-2-5 3d/game stable - must of been early batches as well :)
these results make me soooo jealous :( :slobber:
i've tried my sticks with 2 opteron 146's, an X2 4400, a 3000 winchester and a 3000 venice, two different power supplies, 2 gfx cards and 3 different motherboards all with the same result, i just can't get above 258-259MHz without the monitor going crazy :confused:
i'd be really happy with 270MHz :stick:
You know that, I know that, the G. Skill tech in this thread thinks it is an IC problem, which is why I wanted to pin Tony down on what exactly he is saying here. 250 MHz fits perfectly for my 24/7 overclock on a divider so I was prepared to wait for these EB's to come back in stock, but who knows when that will be and Tony's post makes it seem like a crap shoot whether my mem controller can handle them or not so I'm back to Crucial I guess. Thankfully they cross-ship!Quote:

I have to say that my sticks pass 285 in memtest for hours and one even rached those 290. Can't be just tyhe controller but I agree has to be something with it too.
Thing to remember is it's a combination of both, the way the memory controller plays with this IC, it gives you trouble in 3d. This doesnt happen with other memory, but you need to remember that a weak memory controller is just that, and crucial isnt going to fix it any better than OCz does. Plus, if you are only running 250, then this memory is good for you, as OCZ sells this as a PC4000 product you are gurantee'd that speed, unless i am mistaken you should be able to return them regardless of if it is your memory controller or the IC's themselves.Quote:

Thanks for looking out, Revv23. :) No illusions here on what Crucial can and cannot do for me, just with Crucial I can have a lot more flexibility in chosing what HTT and dividers give me the best oc and bandwidth. Besides that my inability to get a staight answer out of OCZ over at the bleedinedge has me so frustrated I am definitely not going to wait for these EB's and am cancelling my Powerstream order as well.
thikingbear, the advantage of going to OCZ is the fact that with Crucial people RMA the memories 1 or 2 times a month. With OCZ you will get rock stable memory. I don't know how important that is for you but for me I hate to have to RMA memory. I end byuing another memory set then I have to sell when I get the rma back.
In my opinion (as a costumer) I would go 10 times for OCZ instead of Crucial. The other brands are way bellow.
Guys if you want my honest opinion I prefer 4000gold to 4000EB, some of our UCCC has awesome headroom now and it real easy to set up.
Infineon are producing again so supply should come good for those waiting, we are also checking new IC's all the time so please don't think we are sitting still on this.
Load and timings are the issue with 3D i feel, plus the internal draw particular IC's have. The micron die may have less load than the infineon die so making 3d fail before it did on the micron..hard to say without measuring etc and being honest its not really worth the time playing.
4000EB is rated at ddr500, there is headroom but its not guaranteed.We see a lot of RMA purely due to the modules not overclocking as high as the end user wanted...this is fraud and we may have to tighten RMA due to this abuse. I used to buy twinmos BH5 many moons ago and speed bin it my self, sell of the poor clocking modules and keep the rest, i NEVER RMA'd because they did not overclock like I wanted, i just sold them and moved on...
RMA abuse is wrong, take note of my words here, the support we offer you guys depends on how you conduct yourself with your ram purchases.We support the enthusiast as long as they support us and are fair with us.
Tony what kind of overclocks they getting out of the OCZ Gold GX 2GB sticks I have a friend wanting to get better clocking ram then he has now and i want to see what these are doing in the overclocks. ;) Plus they are on sale right now with a rebate at newegg.
load as in power draw? micron kinda blasts away everything with a blazing fireball ic out of hell ;)Quote:

4000Gold is doing quite well yield wise but I can not and will not quote numbers as every rig is different. Some may see 290+ some may see 267 max etc...
I`d be happy with 265, for me they start at 251. :(Quote:

It seems the Opteron 170 memory controller is quite sturdy. I am surprised I can run 270MHz with a 7ns MAL :eek:
EVA, care to share your timings please :D
EDIT: Also, games seem to be perfectly fine at any frequency... we shall see once I go above 270MHz.
