So I've got my 1700+TBred B at 200x10 on 8RDA+...

[thirdlegstump]

and it's been rock solid for 3 days straight using a stick of 512mb Corsair XMS LLPT 2700 in an 8RDA+ at 3-3-3-6. CPU temps at 43-47c. Vcore 1.625. Aggressive CPU interface.
I'm using a Zalman heatsink/fan.
Should I not go further? I'm a bit worried about frying the chip or something else.
Should I expect more performance by upping the FSB and syncing with memory or should I stop at 200FSB and just up the multiplier at this point? I don't know how much the Corsair can hold up either.
Advice appreciated : )

Oh and one more thing, I want to add another 512mb for dual channel. Would it be able to sustain the same settings or would I have to drop the timings a bit?

Your FSB is already passed your RAM speed, so upping it won't get it any closer to getting the speeds in sync. PC2700 is 166MHz (333 DDR). Your FSB is at 200MHz (400 DDR), so if you want to sync them, lower your FSB to 166 MHz or buy faster RAM (PC3200).

 

[Blooz1]

What kind of temps are you getting at present with the Zalman? You should take that into consideration before pushing your system higher.

also, is the chip a DLT3C or DUT3C???

 

[Necrolezbeast]

Les, I think he means that he has his fsb/ram synched at 200mhz and doesn't know how much more it can handle...just because it is pc2700 doesn't mean that it always runs at 166mhz no matter what, you can change that all you like...

 

[thirdlegstump]

Yes, my system is running 200fsb/400mem in sync. I'm getting about 46c cpu temp with the Zalman.
As for the exact cpu stepping..I didn't really check before installing the heatsink but I do know that it was a Tbred B.
I'm assuming not but are there any apps that can identify the stepping without physically looking at the core?

 

[Doh!]

Aida32 (freeware) will tell you the stepping.

 

[thirdlegstump]

Cool. Thanks Doh!

 

[thirdlegstump]

well it doesn't tell me if it's a DLT3C or a DUT3C.....
Also just tried 10.5x 200 and got a ntsomethingos.exe error so I'm guessing it doesn't like that multiplier.

 

[Blooz1]

Judging by your results at the present voltage, it sounds like a DLT....

As for "not liking the multiplier", you probably need to boost your VCORE. That's why I asked about temps, because usually added voltage will also increase temperature....

 

[thirdlegstump]

very cool (no pun intended)
Which is the better chip? DLT? DUT?
The thing is, when I tried to boot with 10.5x200, I couldn't even get into the bios. It just got stuck at a black and blue truncated screen. I had to jump cmos and reset. If that's the situation, would increasing VCore help?

 

[Killrose]

Yes, try upping the vcore, probably to 1.675-1.7v and try it. I usually start suspecting CPU limmits when you can't even at least boot into Windows though. Having the bios crash like that can mean real troubles.

 

[thirdlegstump]

so would you recommend that I stop the overclock at 200x10 default Vcore or are you saying it's safe to bump up the Vcore and go further since it won't/might not crash the bios?

 

[meowmeowmeowmix]

Man, don't overclock anymore than 2.133ghz, I had an 1700 TB B on an 8rda+ and it was find at a 2400+ or a 2600+ but no, I had to push it too the max then I fried my motherboard's voltage regulator. Now the highest my voltage can go is 1.3 V, just enough to run my underclocked processor at a 1500+. Don't push it farther than 2.133Ghz, its just not worth it.

 

[thirdlegstump]

hmm.

NO. Go ahead and raise your vcore. Don't know what you are at by now (with your vcore), but usually if it does'nt boot past bios screen, you have to jump the vcore by a couple of voltage increments, not just one. Let's say 1.626v is a no go, you'd better plan on raising it to 1.675v or more for that sort of problem.

Yeah, dear god, up that voltage Get the most out of that chip. In my experience, I've NEVER seen anyone kill their chip with voltage directly... but rather, indirectly with heat. Voltage itself probably won't ever kill your chip. I've heard some people talking about that it 'shortens the chip's life' or something similar, but no hard evidence seems to back that. As long as you have a decent hsf+fan, you should be able to raise another .2 or .1 vcore just fine.

As far as the ram question... you should be able to hit 200 just fine with those timings... maybe a little faster from what i've seen. Good lucK!

 

[thirdlegstump]

Kill, JH, thanks for the comforting and informative replies. I'll try kicking up the Vcore a bit and push the fsb in sync with memory just a bit more. Geektech rocks! (I mean anandtech..)

 

[thirdlegstump]

bah, it won't go further even at 1.7V

 

[LastRide]

I am at 220FSB with 10 multiplier on my 8RDA+ A1/C1 northbridge and it can go higher,but never bothered.Vcore voltage is at 1.75 and CPU temp is 38C at idle.Running right now at 200 FSB with 12 multiplier 2.4GHz on the 1700+.
