aciddance Posted January 17, 2006 Posted January 17, 2006 I can't even get it to do 205fsb no matter what timings I give it. What could be wrong with this crap? Quote Share this post Link to post Share on other sites More sharing options...
Sir. BOBSONATOR Posted January 17, 2006 Posted January 17, 2006 i lolled.. sorry i cant help you though.. Quote Share this post Link to post Share on other sites More sharing options...
red930 Posted January 17, 2006 Posted January 17, 2006 I can't even get it to do 205fsb no matter what timings I give it. What could be wrong with this crap? To be fair its only rated at DDR400 (PC3200), so it might not go any frther than that. Quote Share this post Link to post Share on other sites More sharing options...
aciddance Posted January 17, 2006 Posted January 17, 2006 To be fair its only rated at DDR400 (PC3200), so it might not go any frther than that. yeah that kinda sux though, I bought some cheap . for one of my other pcs and I put it in the new machine and it is doing ddr500 @ 2.5 3 3 8 at 2.6v. Atleast I got lucky with this stuff. I will just sell the pqi crap to a friend that doesn't oc. Quote Share this post Link to post Share on other sites More sharing options...
before Posted January 17, 2006 Posted January 17, 2006 As far as I know pqi uses TCCD for Turbo sticks. I've a pair of Turbo Relaxed Latency PC4000 and there are not more, not less, than TCCD 507 with PCB brainpower which is among the best of TCCD chips. My sticks bench @308MHz 2.5-4-3-7 with only 2.7V (instead of the rated 250MHz 2.5-3-3-7 @2.7V) and I've tried memtest up to 314MHz after validating stability @300MHz 2.5-3-3-7 @2.6V for 1 hour of looping memtest #5. First of all, would you mind telling me the exact name of your sticks: the manufacturer list is here http://www.pqimemory.com/turbo_double.asp Quote Share this post Link to post Share on other sites More sharing options...

before Posted January 18, 2006 Posted January 18, 2006 I've sent an email to a pqi contact person (I'm a professional reseller so it might help ) in order to be sure your sticks are made of TCCD chips: the rated timings 2-3-2-5 @200MHz are puzzling me as it seems me that TCCD would made 2-2-2-5 @200MHz like the PQI3200-512DBU... :confused: Let's see! TCCD are usually hard to tweak anyway... As you've probably noticed there’re bioses that better support TCCD or BH5; etc. Check here You may wish to use a "-1" bios for TCCD. Once you've a bios that supports more precisely TCCD, may I suggest you to try these settings in the Bios (quite tight for using @300MHz and above, but actually quite relaxed @200MHz): Vdimm : 2.8V tCL-tRCD-tRP-tRAS : 2.5-3-3-5 tRC = 7 | tRFC = 14 | tRRD = 2 | tWR = 2 | tWTR = 2 | tRTW = 2 | tREF = 4708 | tWCL = 1 | DRAM Bank Interleave = Disable | DQS skew Control = Increase Skew | DQS Skew Value = 255 | DRAM Drive Strength = Auto | DRAM Data Drive Strenght = Level 2 | Max Asynce lantency = Auto | Read Preamble time =Auto | Idle Cycle Limit = 16 | Dynamic Counter = Enable | R/W Queue Bypass = 16x | Auto Bypass Max = 7x | 32 byte Granulation = Enable(4burst) OR tCL-tRCD-tRP-tRAS : 2.5-4-3-5 tRC = 7 | tRFC = 14 | tRRD = 2 | tWR = 2 | tWTR = 2 | tRTW = 2 | tREF = 4708 | tWCL = 1 | DRAM Bank Interleave = Disable | DQS skew Control = Increase Skew | DQS Skew Value = 255 | DRAM Drive Strength = Auto | DRAM Data Drive Strenght = Level 2 | Max Asynce lantency = Auto | Read Preamble time =Auto | Idle Cycle Limit = 16 | Dynamic Counter = Enable | R/W Queue Bypass = 16x | Auto Bypass Max = 7x | 32 byte Granulation = Enable(4burst) If you prefer tweaking with A64tweaker check this screen (but I've experienced some obvious freezes while tweaking TCCD with A64tweaker): [Edit: I've used the 623-2 bios here but I wouldn't recommend you to do so] Quote Share this post Link to post Share on other sites More sharing options...

I had almost given up on this ram for sure since my cheap stuff is getting such decent numbers right now. Quote Share this post Link to post Share on other sites More sharing options...
before Posted January 19, 2006 Posted January 19, 2006 So, I've received an email from pqi, and as I was thinking about when looking at the timings, yours are not made of TCCD chips... Sorry dude; but they can't be bad anyway! :nod: 2-3-2-5 are not timings available for all RAMs. May I ask you to take a screenshot of your timings in A64tweaker while running at stock parameters?
