DDR2-1066 using a 4X1GB config on AMD chipset/Phenom

[nanohead]

Anyone tried this yet? I've read both pro and con, but am not sure ATM.

The 2x2GB are still pretty expensive, whereas 4GB using the 2x1GB sets are half the price with those silly rebates in most cases...

I already have some OCZ 1066 2x1GB mem, and was wondering if adding another set would give me speed problems. ???

I've been running 4x1 G.Skill 1066 with no problems @ 250fsb/800 divider. As a side note, your board doesn't support 4x1 on the 1066 setting. You will need to use fsb to bring ram speed up.

you are kidding here right? i dont really want to go track this down in the mnaual, but this just seems stupid.

seems your not, quote from manual:


that is just plain stupid if you ask me, nothing on the box to say this ehhh?

plenty to say it supports 1066 mhz though

disgracfull, i was hearing great reports about this board too, all piontless now.

wouldnt take it if you gave me it

on my foxconn i have a problem booting 4x1gb @ 1066... it posts fine and when i choose xp or vista both of them give me an error saying part of the windws setup is missing, the typical memory related error. i know its not the ram because i can run them @ 1000mhz 4-4-4-12 and it just wont load windows when set to 1066. and i was going to try some 2x2gb kits but i have to take my heatsink off to get the last ram module out so i said screw it i can live w/ 960mhz 4-4-4-12. i would like to know if anyone knows some affordable ram that could run 1066 w/ 4x2gb?

I tested three kits (4x1GB) in three 790gx (DFI JR, AsRock AOD790GX, GBT790GX) boards.

The only kit's working in 4x1GB 1066 are Crucial Ballistic Tracers. It works in all three boards atleast with 5-7-7 timings.
I also tested GSkill 8500PK's and Kingston Hyper X. Both work in 1066 mode with two modules but not with four.
Worst was 4x1GB GSkill in GBT board. It did not work with 4x1GB in 800 mode (not 100% sure if I had other issues here).

On the GSkill kit there is an EPP mode for 533 and that mode requires an higher tRC than K10 can offer (guess it's 42 max), so i think that is the limit described in the manual. The Tracers require a lower tRC (~33) for 533. The Kingston Kit did not have a profile for 533 mode but I assume it would also require an higher tRC than K10 can handle, because it was an cheak kit like the GSkill PK's.

Did not kown about this two dimm limitation, so thanks for posting soundood.


Found this in the BKDG. I read this as one channel with two slots can only run one module in 1066 mode, so it is a architecture limit here.
Now I wonder why the tracers work.


Here I can get an 2x2GB Apogee Kit DDR2-1150 for 128€ and two Tracer Kit's set me off 64€ each. I ordered that Apogee kit already but one module was defect. Plan to run four off em in future hope they will work in 1066 mode like the tracers.

the thing is here is that i have 2 x 1066 mhz crucial ballistix, they seem to have trouble in my AX78, they run for weeks no peob, then i start to get random blue screens.

that isnt too much of a prob, as i intend to get a new Nvidia ACC mobo as soon as they appear, but i was thinking that i could just get another 2 crucial sticks to match the ones i got, and plunk them straight in there.

seems i might have a little hassle, if i choose the wrong board, so i got to get myself 2 x 2 gig sticks....more cash now.

i just think if it 'support' the speed, it should do in evey slot.

more AMD referance rubbish

Yep i know ...Im using 1066 2x1gig and and read that too... I may grab the DFI790fx/sb750 if this dosnt play right with 1066mhz

I've been running 4x2GB at 1066MHz on Asus M3A32 MVP Deluxe even when memory was rated at 1000MHz w/o probs. It's all up to the board and BIOS options, not the CPU.

what ram are you running?

[Rammsteiner]

Ive 4x 1GB Transcend Axe RAM 1066+ in my system for about 9 months. Used it in 790FX-DQ6, UT 790FX-M2R and now in DK 790FXB-M2RS. Didnt try 1066 setting on this board but to be very honest, Im not interested at that. But both previous boards ran DDR1150 with the use of 3:8 mode no problem.

It's just I prefer DDR1000 4-4-4

pfff... here we go again 'cos your mobo doesn't support it it doesn't meant that all others mainboards out there don't support it... I know for a fact that DFI 790FX mobo can run 4x1 GB DDR2-800 O'Ced @ 1066 MHz in Ganged mode

[EXxx]

i just received my crucials, so now i have 4 gigs, i`ll post some test with them oc`ed, this week-end (hopefully i`l have some time)

[HondaGuy]

Here are my Tracers LED PC2-8500, 4x1Gb

My comment about running 4x1, 1066 in the northern part of this thread wasn't meant to put everyone into a tailspin. I thought this was general knowledge and I was just restating the obvious. I checked the memory QVL for my other board, a Gigabyte GA-MA79GP-DS4H.............it states the same..........'due to AMD AM2+ CPU limitation, DDR2 1066 is only supported by 1 dimm per channel.'
That being said, the deal with running 4x1 is probably YMMV depending on the board and ram being used. I haven't tried running my G.Skills at 1066 because I happened to find that statement in the Asus manual prior to installing the second set of sticks........so I initially set them at 800 and clocked the bus to 250.
Peace out..........

lol this little bully just doesnt give up ehhh?

ok Nedjo, it would have helped your reply if you had actualy read the thread properly. i didnt say my board doesnt support 2 x 1066 ram, or 4 x 1066 ram for that matter, i said my board has trouble with the crucial 1066 mhz, this is a known issue in the AX78, so thats that really.

but you will also be overjoyed tio know that the AX78 does in fact support 4 dimms of 1066 ram that is on the compat list. funny ehhh? the so called cheapo board supports it but..........

the OP's Asus M3A79-T doesnt? as it states in the manual? yeah the post a few above yours? did you even read it?

yes the Asus M3A79-T is the board that we are talking about? not my board?

yes this is one of the 'other' boards you refer too, and if you check the rest of the posts you will find some more of your 'other' boards you are refering too.

got it yet?


now maybe?


penny dropped yet?

lol, you are such a little bully boy ehh? hunting down my threads in earnest to comment on thm, to the point you dont even know what your talking about.

ownt

I read the following on another forum HERE. KTE use to post at xtreme but is no longer doing so.

Every 2/4x2GB or 4x1GB kit installation I've come across right from the MFGs to OEMs to distributors and customers, with K10, have had problems at stock getting stable until they start troubleshooting and following the recommended procedures. BSoD/Freeze is how it shows up usually, so that is certainly not unheard of nor uncommon. Most of the boards around have poor high density or high volume MEM support. Many require tRC to be higher than what K10 IMC allows to run at stock. A complaint I made right at the very start in December to AMD.

MEM support and stability is also heavily a board to board orientated luxury. Gigabyte typically has the most atrocious I've yet seen (or, many low-end).

I also quoted his advice on reseting memory MAL and latency HERE to get your ram to work.

[dball3]

crucial seems to have a problem with their ballistix 1 gig sticks , I have four , and they have given me alot of problems. Even if i just run two at a time. the number on the sticker is 97433. I have seen problems on alot of forums

[Manicdan]

on my K9A2 plat, im running 4x 1GB patriot 800mhz cheap and simple decent ram, and i run it at 1000mhz at 2.2v on a BE X2 5000+ if i change the timings to 5-5-5-15 ive pushed it to 1200mhz. not sure if this info applies since its not a phenom, but hell it dosnt seem hard at all to do 1066 in all 4 slots with OCing

This is what I was asking, I guess I was too lame to RTFM... I have the MA79GP-DS4H also, and was trying to cheap out on getting the 2x2GB kit. I have a set of 2x2GB Reapers in the Asus M3A79-T at 1066, they run fine.

I OCed using Multi due to simplicity and my naive belief that ACC actually does something, so HTT based OCC has become a thing of the past for me as I've become spoiled by all these BE processors (I lie like a rug... I'm typing this on a machine running my trusty 8650@ 235x11.5=2.7Ghz)

[RiverRicer]

No, not lame.........but it seemed to open a can 'o worms for some posters. Hair on fire and all that!

You're probably best off if you bite the bullet and buy a 2x2 1066 kit. I'm going to end up doing the same when I put the 9850BE back in the Gigabarf and swap out my trusty old EVGA/5000BE combo........that's going in the old woman's rig (sans the Tru 120....need that for the 9850).

And hey, you're missing out on all the fun by just jacking cpu multis!

[Aussie FX]

I have been able to run 4x1gb 1066 either Team or tracers in 2 GBT boards. One 790GP and a 790FX-DQ6. Both sets of ram are using D9GMH.

I have 2x2gb tracers shipping now. I want to try those combined with 2x1gb.

I will post the result when they arrive.

[SkullCracka]

been running @ 1066 with tracers in my m3a32-mvp for like 8 months. hmmm strange they seem to work fine. 5-5-5-15-30

i get video driver error now and then but dont think that has anything to do with the ram. maybe it does. ill try 800 with 4-4-4-and see how it does.
