this is my first forum post, probably ever. But I don't know where else to go. All my friends with years of experience are at a loss for words when it comes to clocking.
MY SPECS
thuban x6 1100t 3.3 ghz stock
zalman 110 CPU heatsink
Corsair vengeance 2133 2x4gb
asus m599fx pro r2.0
wd caviar black 1tb
Dual 7850
750w cougar psu
so this computer I've dropped a lot of my work money to get nice parts is going really well. I just need to finish it off my synchronizing my CPU and ram sticks I'm having trouble because when I turn docp on to have ram at 2133 it automatically overclocks the CPU to keep up with it. I did some google research and older series cpus has to overclock to keep up with the ram. So my question is should I try and overclock the CPU? Change the multipliers down? i would just like to have a stable computer with those ram speeds seeming as I spent the money on fast ram. I had a 100 frame boosting csgo when I upgraded my ram. hats a large increase from 100 steady to 260. If anyone has ideas let me know. under full loaf my heatsink gets to be about 52c
Im adding some more information to this since I made this post last night on my iphone 4. I am trying to overclock my cpu. when i set the memory to 2133 then my cpu jumps in frequency to 3.8 or 4ghz. Should I change the voltage? Should I keep playing with multipliers until my computer stops having errors in prime 95. Thank you in advance for at least reading this post.
How are you setting the memory speed? You should just be able to change the memory multiplier without it effecting the CPU speed.
You should be able to OC the Ram without OC'ing the CPU. A Friend of mine runs his 1100t @ 4.4Ghz and his Ram at Stock 1333mhz. So it should walk the other way around, but why would you have the Ram at 2133mhz? I don't think it will make any difference in gaming. BUT if you MUST run the Ram at 2133mhz than just go into the Bios (UEFI) turn the XMP Profile on that is for 2133mhz and turn the multiplier of the CPU down till it runs at ~ Stock speeds.
well i bought this 2133 ram because it was the same price. When i go to the ai tweaker tab in the bios it has 3 options. manual, auto, docp. The ram only goes above 1600 if the setting is put to docp. So when I click on memory frequency and change it to anything above 1600mhz it automatically clocks the cpu up. So eg. 2133 i get 3.83 ghz. But its unstable. So when i turn the cpu multipliers down from 15 to 13 to get 3.3ghz then the computer blue screens and crashes.
Thats a picture of my setup. Its clean. I just want the bsod's to go away and have a stable system. My last ram was 3x2gb crucial 1600mhz triple channel. Which as we know amd only does dual channel.
So when you say memory multiplier is there a specific setting to change the multiplier for the ram?
I have a good tech background too. 5 years doing computer work. I work at a computer shop now. A+ Network+ certified.
Hopefully this gives you more of an idea on what im working with. I can take pictures of my bios when I get off work in a few hours.
Are you sure the bsod is because of the CPU OC? Have you ever OC'ed just the CPU just to check that this is the reason why the system failed? I mean it could be the Ram, your motherboard just supports 1866mhz Ram and 2133 is "OC". I would try to OC just the CPU and if the same happens we/you know it's definitely the CPU.
well I have an old am3 board that i got with the computer before i started upgrading. The cpu was previously overclocked on that computer and stable at 4.2ghz. But i didnt overclock it my cousin did. That overclock was lost when the bios reset itself so its not like i can transfer the voltage settings over.
I mean im assuming the only reason its unstable is because there is no constant voltage set. But then again i dont know. I mean it seems more like overclocking failure when I get the bsod. And i just got a new motherboard from asus because my dimm slots on the other one gave out due to esd from a family member.
I dont know how to overclock in the first place. When I turn my ram to 2133 it just ups the cpu by itself. Is there a video for creeping the cpu to overclock? because i have no idea lol.
What appears to be happening is that in order to achieve higher ram clocks, the motherboard is increasing the FSB multiplier, in turn increasing the CPU clock. Simply up the voltage on the CPU a bit, until it becomes stable and live with having it overclocked accidentally.
Certifications mean nothing to anyone who is not an employer.
3.8 ghz is a pretty mild overclock on the cpu. If you aren't against overclocking your cpu, you may be able to get it stable by bumping up the cpu voltage .05-.1 volts.
Okay i see what you are saying. Yes I can live with a stable overclock. so I should put it back at 2133 and then when it auto overclocks I should go down to voltage offset, voltage change on cpu and try to increase it until i have no more errors or blue screens? I can do that. I am just glad there is nothing i have to do that is too complicated. :D I did some research on the cpu and it seems that it can hit 1.45 v without burning up the cpu but ill start at 1.37 and work my way up. Ill make another post saying how I did. Now I should run blended prime 95 tests for benchmark for at least an hour?
after some more research my stock is 1.396v and it is safe up to 1.55v which is overkill. And with that cooler I should stay relatively cool. Thanks guys. Ill give an update on the stable rig. I cant wait until i can play watchdogs and csgo again. maybe ill break 300fps in csgo ;)
So I have been playing around. Got to about 4ghz with ram frequency 2128 at a 15 multiplier at 266. technically 3.990. I set the voltage to 1.4ghz. Should I manually set my voltage for my ram and motherboard while im at it?
well i started at 1.4 for the prime 95 benchmarks. and im up to 1.45 at 3.99 overclock and its still giving me "FATAL ERROR: Rounding was 0.5, expected less than 0.4" it seems my voltage is still too low? im looking at cpuz and my ht link, core speed, bus speed, core voltage and memory clock fluctuate only ever so slightly. Ill keep upping the voltage for the core cpu. But if i hit 1.49 and its still not stable I might ask for a second opinion on those other voltages.You guys are a serious help and I love you.
viewing from cpuz my voltage core clock goes from 1.44 to 1.476 when running prime 95. If that helps anyone
aBios. Kinda lost. I've tried some voltages starting with 1.375 and working my way up to 1.47 nothing seems to be stable even on a 3.8 clock. I just keep getting a 0.5, 0.4 expected worker has stopped then 2 minutes later a blue screen. So I googled the phrase. It means to up the voltage. So + fer plus i did that and prime 95'd every clock for 2133 ram. at 3.990 ghz. Once I got to 1.47 the computer would refuse to boot. Maybe there is a problem in my method.
Phenom cpu's have upto DDR2 1066 - DDR3 1333 memory controllers running higher that that can cause errors geting the ram to work at just 1600mhz can be challenging on the old Phenom/thuban cpu's.
Well after talking to my buddy who runs an fx 6 core he mentioned how even his 2133 ram is funky. that he has to drop his mhz down to 2000mhz. so I changed the cpu frequency to 250 with a 14.0 multiplier and im at 3.5ghz right now on auto voltage. My northbridge/cpu voltage in ai tweaker is set to a 1.16v from the original 1.15v and my ram is working perfectly. and so is my cpu. Ive been prime 95 testing it with blend and no more fatal errors or blue screens. So what I am probably going to do just leave my cpu voltage at auto and leave it at that. Hopefully this helps someone using a Thuban. These are nice processors and I was not willing to spend 200 more dollars on an fx 8 core. Also my ram is set to 1.65v static which is also the stock. This was a great idea thanks guys. :D
