VDroop Question

[Butterz]

so i have been trying to push this chip with the core 2 duo e6700 stock it only has a fsb of 1066 so far i have pushed it to 1368 fsb the board is rated for 1333 fsb the ram is rated for 1333 but cpu-z says it can get this high. so anyways i have been running OCCT for about 11 mins now and so far so good but i was hoping to use a cpu ratio of x 10 right now im at x9 my voltage is at CPU Voltage 1.45000 - VTT Voltage 1.35 - DRAM 1.53 - NB Volt 1.251 - GTLRef Volt 0.63vtt. now i have seen the graphs from OCCT and i have a vdroop or drop my question would be would i be safe to push on more voltage for the x10 multiplier?? my board is really old tbh ^_^ (max voltage on board for CPU Voltage is 1.60000 Max VTT 1.50)

Current readings in OCCT:
CPU VCORE 1.32V min 1.34V max
+3.3V 3.38V min 3.39V max
+5V 5.06V min 5.09V max
+12V 12.82V min 12.88V max
100% Load OC%(Bus speed 28.7%)(cpu 15.6%)

Have a look to see if your board has something called Load Line Calibration. It's a feature to reduce vDroop and keep a consistent voltage. However on older boards the feature was a setting of On or Off and usually it used to overshoot, depending on how good the board is. But if you have the option give it a try

the ram is rated for 1333 but cpu-z says it can get this high.

CPU-Z should be reporting 667MHz for RAM speed (DDR - 2x 667MHz = 1333MHz)
for slotX and the same for what other slots are populated.

so I have got it stable at x9 342MHz and I found a stable voltage for x10 but temps kill the stress test since I do not want to go over 58c the chip is rated for temps up to 60c also I have a screen shot of what cpu-z says for the ram!! but can you guys tell me if I am wrong if I was to put it to x10 and bump my voltage up to 1.56875v (Bios) in cpu-z says 1.463v and got a new cooling system would I end up frying the chip from voltage (Chip Core 2 Duo e6700) Max voltage is 1.5v. I have looked in my bios and I do not see any kind of setting for load line I also have pics of the bios screen I am a newb when it comes to voltages I always just pushed the chips till I had to do voltages.

OCCT Test Results: Voltage Settings: VTT Voltage 1.35 CPU Voltage 1.43750 (Bios)

+12v

+3.3v

So I just finished running OCCT LinPack Testing my oc failed at VTT 1.35 so I gave it a boost to 1.40 and it passed. I ran the test with 90% memory used max temp was 59c so I guess I found my limit for the chip till I get a custom loop installed but that is not going to happen lol not for a few years!! but I would still like to know the info and advise on the voltage since I do not want it to be a paper weight!! I'm trying to get x10 instead of x9 since that would increase the GHz.

ooooo 775 overclocking. so much fun.
getting to a 10x multi is never a sure bet. try a heap of different configurations.
trail and error. also try using just one stick of ram.
i would be tempted to go up to 1.45 just to see how high the chip would go. then scale it back to a modest voltage like you are currently running.

My problem is if I go any higher the voltage is really high in bios but when windows is up the voltage drops!! so would it be a safe move to go past the 1.5v mark on the chip? so long as I can keep the temps down.

1.5v + for 24/7 is not the best idea if you want your cpu or board to last. it'll be a hell of a lot of strain on your boards hardware.
The vdroop is a safeguard of the board to backaway from damage.
There may be settings like eist or something like that. From memory its power saving stuff. So disable all that.
Remember that not all cpu's overclock the same. Some just reach that point of failure.
See if you can grab a good chip like a q9550 (eo stepping) or a QX chip. You will have a lot more fun overclocking them.

well I am pumping this up for my daughter & myself for the time being I have a 3770k sitting here waiting for my new rig to get built. so you say to disable the power savings and that should help on making it more stable at mutli 10. should I get worried if in bios it says more then 1.5v on vcore? but in windows it goes down to say 1.483v or less then 1.5v? if the pc is going to be on for 24/7 I would lower it back down to a lower voltage and back the clocking off but right now its only on for about 8hours to 10hours.

Update To my changes:
Now sitting at 3.33GHz Details: 333MHz x10, FSB 1333, VCore 1.52500v = 1.472 (in Windows) 1.52500v = 1.541 (in Bios) VTT 1.40v, Temps Idle 40c - Load 59c, PCIE Freq 100MHz. OC Rating 25% 3.33GHz

Do you think that would be fine? I really don't want it to be a paper weight! I tried backing it off a bit to 3.20GHz but it didn't change the Temps the power dropped just a bit like to 1.46 in windows.
