FremontCA Posted May 29, 2009 Share Posted May 29, 2009 After reading through this forum and other forums I'm under the the impression that my two sets of TR3X6G2000C8GTF have problems. Problem #1: There should be multiple XMP profiles, but neither of my two sets have more than 1 profile and it is only for 1866C8 settings. Problem #2: Even if I manually set the timings and voltage to the 2000C8 settings and OC my mobo/cpu a little bit to get 2000, it is not stable at all. Problem #3: Both sets of TR3X6G2000C8GTF pass memtest+ at the 1866 settings (XMP Profile1 or by setting it manually), but fail at the 2000 settings. I'm running an i7 920 on the EVGA x58/Classified motherboard. I've already sent in an TSX ticket, but it's been 3 days with no replies or responses. Can I get some help please? Thank you.

Corsair Employees RAM GUY Posted May 29, 2009 Corsair Employees Share Posted May 29, 2009 I don't think that any I920 CPU will run with the memory at 2000 MHz with one module let alone 3 or 6 and with two sets of these modules I would suggest setting the memory frequency at DDR1600 and set the memory Voltage to 1.66 Volts and set the QPI Voltage to 1.6-1.7 Volts and see if the system is more stable. And leave the timings on Auto and set Command Rate to 2T. Link to comment Share on other sites More sharing options...
FremontCA Posted May 29, 2009 Author Share Posted May 29, 2009 If that is the case that the i7 920 cannot run the memory at 2000MHz, then does that mean I need to upgrade to a 940 or the 965? I'm only asking because it was not made clear or stated on any documentation or marketing material that says to run the 2000C8 sticks at rated specs, I need to meet a minimum processor model. btw, I'll be at Chipotle later on Automall pkwy... wanna bring me some freebies? :laughing: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 29, 2009 Corsair Employees Share Posted May 29, 2009 The I920 and I940 CPU's only support DDR1066 they will over clock to DDR1600 with out too much of a problem, however it is still over clocking no matter what CPU you have and hit and miss, Yes the I965 would have a better chance at 2000 MHz but not with 6 modules.

FremontCA Posted May 29, 2009 Author Share Posted May 29, 2009 I tried the following with 1 set, then the other set and neither are sets of ram are stable: CPU Ratio: 20 BCLK: 143 Ram Divider: 2:14 8-8-8-24 (everything else auto) VTT = +350 (this is what XMP sets it to so I use it for manual configuring) vDimm = 1.65 or 1.675 All other bios settings on auto/default/stock What surprises me is that it's only an BCLK increase of 10 for overcocking and from your statement that it's a hit or miss for OCing, I think it's either a very narrow window of opportunity or something is wrong with the sticks I have. My system as a whole can run stable overclocked at 21 x 200 with the memory running at 1600MHz. With this observation, I have a hunch that it's not the platform that's having the issue. I have also used 3 different 920 processors and 3 different notherboards, 2 power supplies, 2 video cards and several different hard drives. After reading a recent post about another customer running their 1866 up and above Corsair specs (in fact above 2000C8 specs as well) on an i7 920 platform and I cannot get my 2000C8 to run at manufacturer's specs, it's tough to believe that it's my system/platform that cannot support 2000C8 memory.

wetfit9 Posted May 29, 2009 Share Posted May 29, 2009 If it is true that no I7 920 can run 200mhz, I am mad, because I just wasted money on RAM that will not run at stated speed. That should be posted somewhere. I am having the same problem of not being able to run mines except it is on a Gigabyte X58-UD5 MoBo. I am in the process of RMA's them now. I cannot get a refund from NewEgg, so it would be a waste of my money and time. Please post that information everywhere if that is the case. I just fine it hard to believe also. Well I guess I will have to wait until newegg run out again and ask for a exchange and when they don't have anymore they will issue a refund. I just hope in happen's in the next two weeks.

Wired Posted May 29, 2009 Share Posted May 29, 2009 If it is true that no I7 920 can run 200mhzThat's not what he said. He doubted, not definitively stated it. Hit it with liquid Nitrogen and it's certainly possible, but no one can guarantee an overclock. Just because the memory controller won't hit 2000 doesn't mean the memory won't. It just means you'd need a different CPU. Link to comment Share on other sites More sharing options...

wetfit9 Posted May 29, 2009 Share Posted May 29, 2009 I don't think that any I920 CPU will run with the memory at 2000 MHz with one module let alone 3 or 6 and with two sets of these modules I would suggest setting the memory frequency at DDR1600 and set the memory Voltage to 1.66 Volts and set the QPI Voltage to 1.6-1.7 Volts and see if the system is more stable. And leave the timings on Auto and set Command Rate to 2T. Is it not what he said. "I don't think that any I920 CPU will run with the memory at 2000 MHz with one module let alone 3 or 6" Let me know if that is not what I read. I understand that if you are trying to run 12gb, you will not be able to run at stated speed, but 6gb(3 sticks) you should. If this is not the case I am sorry, but going by what I read. :mad: Link to comment Share on other sites More sharing options...
FremontCA Posted May 29, 2009 Author Share Posted May 29, 2009 Currently with either kit installed, it will not run at rated specs. And these are pretty expensive kits so I'm hoping for support to match the price of this product versus the other products. Ultimately (and this is the key word here), I am trying to get 12GB to run at rated specs. But I'm taking baby steps first so let's see if we can get both kits to run at rated specs by themselves.

Corsair Employees RAM GUY Posted May 29, 2009 Corsair Employees Share Posted May 29, 2009 I am sorry but I doubt that 12 Gig or 6 modules will be able to do that but you might get close. You would have to try it and work your way up from a stable starting point. Since Twin or Tri sets are not tested in full configurations there is no way I can tell you what to set. Start at DDR1600 and work you way up from there. Link to comment Share on other sites More sharing options...
FremontCA Posted May 29, 2009 Author Share Posted May 29, 2009 That's actually what I've been doing. I started with 1 kit at 1600MHz 8-8-8-24 +350/+400vtt 1.65/1.675v configuration with the system at 20 x 160 and stepped my way up to 20 x 200. A bclk of 180 to 190 appears to be the limit with just 1 kit. Just for fun, I tried both kits. Surprisingly, it has the same limitations as a single kit - 180-190 was it. That's when I started swapping out processors, motherboards, power supplies, vid cards, etc. But no combination of parts I had on hand would allow me to go full 2000MHz with 1 kit, let alone 2 kits. Note to RAM Guy: I submitted the RMA request for only 1 kit. Can you look into it and change it to 2 kits? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 29, 2009 Corsair Employees Share Posted May 29, 2009 As you over clock the CPU you will need to lower the Memory frequency that is not uncommon, what if you just install one set and load setup defaults and enable XMP is the system stable and running properly?

FremontCA Posted May 29, 2009 Author Share Posted May 29, 2009 With all defaults/auto/stock and then enabling XMP, it works fine with one problem. The XMP sets the memory to run at 1866MHz. Link to comment Share on other sites More sharing options...
Davyboy Posted May 30, 2009 Share Posted May 30, 2009 Well, if you can get it running fine with the XMP profile enabled and everything else on auto, why dont you try raising the memory multi in the BIOS while the XMP profile is enabled so that the RAM is running @ 2000MHz??? Do all BIOS'es on X58 mobos give you the option of raising/lowering RAM multipliers?? I would have thought they did.... On my EX58 UD5 mobo, you can enable the XMP profile, and then you can raise/lower the System Memory Multiplier to set the frequency of the RAM...

Corsair Employees RAM GUY Posted May 30, 2009 Corsair Employees Share Posted May 30, 2009 Can you run CPU-Z and post a screen shot of the SPD tab for both modules? Link to comment Share on other sites More sharing options...
FremontCA Posted May 30, 2009 Author Share Posted May 30, 2009 RAM Guy, I'll get you the screen shot in a bit here. The system is currently taken apart because I want to swap in the motherboard, processor, and vid combo that had the best overall stability. You do not have to take my word for it now if you need to run the info by someone else, but if I recall the CPU-z shows the XMP profile as follows: Frequency: 1000MHz CAS# latency: 8 RAS# to CAS#: 8 RAS# Precharge: 8 tRAS: 24 tRC: 51 Command Rate: 2T Voltage: 1.65 I think I know what you're getting at with requesting the screenshot of the CPU-z. If I do not increase the default system bclk of 133 to 143, the memory will not run at 2000MHz. It will run at 1866MHz. This also tells you the system puts the ram divider at 2:14 as default. Odd numbered dividers are not an available option. Only even numbers are available. I'm not sure if you were making this suggestion in an earlier post, but it appears you or Corsair cannot guarantee the memory to run at rated specs if the system is overclocked. But at the same time, without overclocking of some sort, I cannot configure the BIOS to run the memory at rated specs. Even if I did decide to increase bclk to 143, then it is not stable anyways. Either way I'll put my system back together here and get the screenshot for you. I need to make sure I remembered it correctly. Link to comment Share on other sites More sharing options...
FremontCA Posted June 1, 2009 Author Share Posted June 1, 2009 Here's the screenshot from CPU-Z of the SPD tab: http://img207.imageshack.us/img207/1174/cpuzn.png It's the same for every slot. For some reason the serial number never shows up. Link to comment Share on other sites More sharing options...
FremontCA Posted June 1, 2009 Author Share Posted June 1, 2009 Ok well, I ran LinX and Prime95 over the weekend with the 12GB @ 1600, 7-7-7-20 and it ran without problems. Trying to do so @ 2000MHz fails every time. So let me ask the question - Running 12GB @ 2000MHz is currently highly improbable? If I happen to come across written accounts of someone doing so, then they just got really lucky and they are not the norm? Link to comment Share on other sites More sharing options...

Yes that is correct, running 6 up is more loading on the memory controller that is in the CPU so if someone was able to make it work they have a better than average CPU.
