Hi there,

 

have bad versions (2.12) of CMZ8GX3M2A1600C9 sticks, cant get it work at 1866 even at 1.65V,

found over google that these versions are difficult to overclock, if someone did,

what frequency(FSB,DDR) did you reach, timings??

 

Thanks

sorry, its there now.

 

have to say they are mixed memory sticks but same versions and same all specs,

also have to say overclock is not possible even with one pair(tried that)

This is what is most likely hurting your OC.That and the memory controller limitations AMD has imposed that Synthohol has posted. That chart came straight from AMD. Basically your asking a lot from your system,unmatched kits and all slots loaded. I wouldn't expect to see much over 1600mhz with that set-up. I know , google says others have done this so you should expect the same results from your system, right? Thats the furthest thing from the truth. When it comes to overclocking there are no guarantees. Your hardware is unique to it's combination of hardware so it will also react differently even if you have the same exact hardware as someone else.

 

There are no known bad batches of this memory or versions either.

Do some systems like certain brands or types of memory over others? sure! But, that in no way means they are a bad batch. Lets not get unnecessary rumors started. These AMD processors are a PIA when it comes to overclocking and trying to get fast memory to run on them . We see it here on a daily basis. They just don't seem to be very consistent across the same part numbers as to what the end user can reasonably expect to achieve,

that table there is bit coinfusing I think - its saying only 1333 for Phenom II, but my 955BE was working lovely without any issues with these at 1600MHz, 9-9-9-24. there wasnt any room for overclock as well, the same thing with current FX cpu, even with one pair couldnt overclock to 1866.

 

Ill try to play with FSB setup, see if it can reach some 1800 at least and let you know any success.

Iam just trying to push it and see whatever it can handle -this is what is overclock about, isnt it??

 

google says someone overclock them nicely up to 2000MHz, someone couldnt overclock them at all-you can go through these reviews http://www.techpowerup.com/forums/threads/having-trouble-overclocking-vengeance-1600-cl9.149695/#post-2353079 and see that all nice OCs are all done with 5.11 versions,

now check this review http://www.legitreviews.com/corsair-vengeance-8gb-ddr3-1600-cl9-memory-kit-review_1740/8 with ver 2.12(same as mine) and it reached max 1866MHz with 1.65V, same here http://vr-zone.com/articles/corsair-vengeance-1600mhz-cl9-8gb-ddr3-kit-review/11921.html/3 max 1800Mhz..

 

So versions doesnt matter?? afaik there always been some "better" and some "worse" revisions.

Dont take me bad, Iam not complaining, just wondering, these are still great products, cant say a word.

OC is lottery at all, joke is I always had bad experience with RAM overclocking at all, no matter what rams or what system - hard to set, stability problems. Not for CPU and GPU, I always had good pieces, running 10-25% higher without hassle.

 

Enjoy your Christmas time :o: , I will let you know with any succes FSB overclock

No , it shows for an FX processor and a MB with four slots populated you would be limited to 1600 with single rank memory and 1333mhz with dual rank memory.

.

Again, you cant expect the same results as someone else. Your looking at one or two isolated systems that have achieved that high of an OC with that memory out of how many thousands of kits sold?

yes, some hardware combinations work better than others, but 99% of the time it's nothing but luck that you get the best results out of any given hardware combination. But because a couple of people have had better luck with one kit over the other doesn't mean they are a bad version. Or that one is better than the other.

I had several 2x4GB Kits with V2.12 and they usually maxed out around DDR3-1800/1866 9-10-9 / 10-11-10 as well. That is very typical for the IC type that is used on those. However sometimes the scaling was actually better at lower voltages (1.4V > 1.5V > 1.65V). Test them one by one and then either use the best pair or just keep memory frequency around DDR3-1600 with four modules.

 

High memory clocks on modern AMD platforms are actually not that hard to achieve. However some mainboards just don't cut it for memory overclocking and knowing some of the basics sure helps a lot :laughing:

thats DDR2400 according to CPU-Z and just about half the bus speed. the superpi results are blacked out. (was it that bad?)

forgive me for being blunt but i fail to see the relevance of the OP's query.

 

trying to OC 1600 ram to 1866 is the format in this thread, can it be done? maybe however as P94's post says

I wouldn't expect to see much over 1600mhz with that set-up.
i tend to agree.

 

there is going to be a set of CMZ16GX3M2A1866 under my tree this year and I have already accepted the fact that populating 2 out of 4 slots with that ram i may not even achieve the rated speed due to AMD's published CPU limitations.

 

lastly and most importantly all the links are showing that ram on an INTEL platform and are not relevant to an AMD platform

Iam speaking of Phenom II, which is maxed at 1333 by that table, but in real 1600 is not problem at all-so I wont rely on that.

 

I'd bet my poor postcommunist wage that different set (maybe ver 5.11 :D:) will do best

 

emissary42: finally useful post! Thanks! So finally 2.12 is not overclocking that well than different IC??

Picture that you post, not ideal timings, what real performance increase did you get with this?? Did you try higher FSB??

You don't really know how to read CPU-Z then, or i don't get what you are trying to say. The kit used is DDR3-2400, but it was run at 1348MHz intead of 1200MHz. DDR means double data rate, so that is DDR3-2696 effectively.

 

forgive me for being blunt but i fail to see the relevance of the OP's query.

First of all: I did quote my own experience with kits using that type of ic. Also i was giving him a hint at lowering the Vdimm when overclocking, because some V2.12 kits don't really like 1.65V at all.

 

The picture was more about what peanutz94 said about these AMD processors being are a PIA when it comes to overclocking and trying to get fast memory to run on them (#7).

 

trying to OC 1600 ram to 1866 is the format in this thread, can it be done?

DDR3-2133+ would be a walk in the park for AM3+ or FM2(+) with the right kit = the right ICs used on that / an other Version number, even when all four slots are saturated. Had he gotten a DDR3-1600 Kit using V4.13, V5.11 or V5.12 type of ICs, there would be a lot of headroom for overclocking. With V2.12 sadly most of the time there is not. That does not make it a bad version for daily use, it is just not what you want as an overclocker.

 

Picture that you post, not ideal timings, what real performance increase did you get with this?? Did you try higher FSB??

The timings are decent for a Samsung 2gbit D-die based kit at these speeds. With higher voltages 9-12-12-21 is possible, but thats about it. The highest binned kit using those ICs by corsair were these:

 

http://www.corsair.com/de/dominator-platinum-with-corsair-link-connector-1-65v-16-gb-dual-channel-ddr3-memory-kit-cmd16gx3m4a2666c10.html

 

So i am not that far off. And I have those as well :D:

 

The performance gain above DDR3-2400 depends a lot on the quality of your APU/CPU sample, because some don't like tighter timings/subtimings at very high clocks. I did try for higher reference clocks before testing memory and probably still hold first place for the mainboard and the APU model used over at HWBOT (179MHz). I don't want to give a direct link here, because i was using other memory for that. Shame on me =)

It's all good. I did go the extra mile and looked for an older screenshot featuring some Corsair DDR3-1600 V5.11 overclocking @ AMD:

So you can do that even with a lower specced kit, but you need the right type of IC on them. There is no model number present in SPD because that was a non-retail Vengeance kit.

So DEFINITELY 2.12 ICs are not that overclockable like other versions. This and its overclocking possibilities was origin of this thread.

 

Recently I stable ran at max 1680MHz 999242T,with irrelevant speed increase (maxxmem),

Much better improvement shows to be setting of timings to 988241T at 1600MHz which run stable for short period of Prime95(all default 1.5Voltage).

 

Next try when Illget to PC will be devreasing timings and trying to reach those 1800Mhz,then some speed and stability testing.

Letting you know then.

Definitely max clocks with my setup are at 1704MHz at 11-11-11-24-2T, with 3% DECREASE in performance,

better way to go is to set timings to 9-8-8-24-1T with previous 1600MHz frequency which makes some 10-15% increase,(MaxxMEM benchmark),

but anyway with only 2% increase in real "gaming" performance (3DMark-IceStorm),

all default voltage 1.5V, succesfull IBT pass, BUT strange NFS:Rivals game crashes(any way to stabilize those high timings with higher/lower voltage??)

 

This is assuring me, again, that RAM overclock is useless(unless some really crazy values).

Memory overclocking is not useless. However with your kit, memory overclocking is not worth it, because you need to relax timings quite a bit for a very minor gain in clock speed. Combined with the lower CPU clock of 4488MHz vs 4515MHz and NB clock of 2137MHz vs 2200MHz in your other screens the result is a slight but measurable performance decrease.

little update- tried to run single pair of memories, both ver2.12 pairs appear to have same capabilities, run at 1866MHz with bad timings at 11-11-11-28-2T, much better result is to improve timings to 9-8-8-24-2T at 1600MHz, with questionable performance increase and stability :p:

 

now iam trying to sell them :o: and get some 2x8GB kit
