How to set up GTL Ref Values for 45nm & 65nm

[Falkentyne]

People, having Loadline Calibration Enabled (or any other vdroop reducer or eliminator) reduces CPU life, CPU needs more voltage and strains system, in my case causes instability in overclocking. I was thinking of enabling it but since its a bad thing I will not.

Having a higher voltage on non cpu use will not raise your temperatures, on load though lets say 1.42 LLC Disabled does less heat from 1.42 LLC Enabled.

The hysteria over loadline is nothing but that..hysteria. It IS true that vdroop is there for a reason, but this is supposed to be for cpus running at *STOCK* voltages and speeds. Yes, Intel knows we overclock; heck they're even overclocking now (and as everyone knows they have taken a more overclock friendly approach than the hardline approach from years ago; witness the extreme editions--who would want an unlocked multiplier EXCEPT overclockers? It's completely absolutely USELESS for a normal consumer).

While it is true that droop is supposed to prevent voltage spikes on load/idle changes, there is still absolutely zero proof anywhere that cpus have been damaged by it. The only warnings have occured from loadline causing -overvolting- at load instead of matching the BIOS settings. There was a huge recent thread about this, which turned out to be nothing but a bunch of hot air and flaming. Oh and keep in mind that vdroop only existed starting with the pentium 4 line. There was no noticable vdroop (at least nothing of this magnitude) on the pentium 3 chips; and those chips used -higher- vcores (2.0 for old P3; 1.75v for coppermines) than what we have now.

I will also tell you this--from personal experience. High voltage does cause degradation, far more so than heat, although each chip responds differently. And it is MORE dangerous to set a higher idle voltage without loadline or vdroop mod, than it is to set a lower voltage and using loadline/vdroop mod, as long as your load voltage doesn't go higher than idle. Voltage is the #1 cause for degradation followed by temps. I had degradation *just* from high idle voltages on a P4 northwood by putting 1.7v idle into it and leaving the computer on idle constantly. Load voltage was 1.62v, a lot lower. And it wasn't the load voltage that caused GNDS here, it was the idle voltage. If there had been a non soldering vdroop mod back then (at least that I had known about and been able to use), my chip would have lasted alot longer without reducing in clocks so sharply.

My X6800 also reduced in clocks (tho not as much as the P4's) by needing 1.55v for 3.7 ghz-which required 1.625v set in BIOS for idle. It was the high idle voltage that hurt the chip; it lost about 100 mhz; needed about 0.05v more. 1.55v idle would have been a LOT easier on the chip. I would have much rather taken the chance with random spikes, than having this happen! And even 1.55v idle was too high; would have been best to have the vcore at 1.5v max (idle) on air.
Subzero completely changes the game.

BTW I didn't know anything about vdroop mods when I had the X6800 either, but my P5W is now vdroop modded and my QX chip hasn't been damaged anywhere near what the X6800 without mod was; there has been very light degradation (something along the lines of 0.01v more needed) but that's it, and I don't keep it at 4 ghz unless I need it anyway.
