It seems I’m limited in getting the core clock to reach 1170mhz even when keeping the memory at 1400mhz. I think 1170mhz core and 1550mhz memory is the maximum I can achieve. I haven’t pushed the voltage beyond 1.240mV with the core. Recently, when I tried to change the core clock from a fresh boot using Sapphire TriXX from 1170 to 1180mhz, my PC would freeze (after a crash), the display would go blank, and the fans would speed up to maximum. Since 1.230mV is clearly high voltage (compared to the factory 1.225mV), I think it’s best not to risk it and leave things as they are.
I don’t have any background processes running at startup except Folding @ Home, which stays idle.
I’m not concerned about core voltage as long as your temperatures are normal. It’s unclear if your card can display VRM temps accurately—if you can, keep them below 85°C. Usually, VRM temperatures are a bit higher than core temps depending on the card.
There seems to be no way to view VRM temperatures for your GPU on these tools. Are there other programs you've tried that might display this data?
What are your highest GPU temperatures during operation at 1.24v with a 1170mhz clock speed? Or what voltages are you using?
I achieve performance at 1170Mhz/1500Mhz when the temperature is 67°C. Adjusting the memory clock to 1520Mhz results in reduced FPS during Valley Benchmark.
High guys this is the 1st time i am posting here.
I ve been following the whole "OC ablility" thing concerning the r9270x and i decided to input my experience.
I ve recently bought a Sapphire r9270x (dual-x fans) 4gb ddr5 while wanting to partially upgrade a rig including an OCed i7 (1st gen) [email protected].
After research i finally got to OC the card to the following rates, using the TRIxx software:
GPU clock: 1200mhz
Memory clock : 1500mhz
VVDC : 1285
Power Limit: 20
Snapshot of my settings >>>

The above settings have been tested with FURmark on 1080p (1920x1080) and 8x MSSA
for at least 15mins with the temperature of the card never exceeding 71 c .
So , do u feel this is a safe OC, and one that can carry out games like BF4?
Is the VVDC setting stressing the card too much?
Is the power limit within the safety limits?
How is the latter actually shrinking the life expectancy of a card?

Will just start off saying this: stop using furmark, it has potential of destroying the VRMs on your card. Use valley benchmark instead.
- Yes the OC is safe, but it might be unstable. A benchmark program can detect some instabilities, but the best stress test is to test your OC in the real world: the game you intend on playing.
- Voltage is pretty high, DO NOT go over 1300mV though. If it is causing concern, download HWinfo64 and check to see the VRM temps under load. 120C is maximum VRM temp on most cards, 90-100C is a good safe limit.
- Yes, theroretically it will reduce the life span of your card. Reason I say theoretically is because unless you plan on keeping that GPU on that OC for 8+ years, you will never run the risk of the card burning out because of the OC (as long as you keep it within safe operating temps). Again, if it is cause for concern, do what I do: Set that OC as a preset in TriXX and only apply it when you are gaming.
I've pushed my system to 1100 GPU Clock, 1500 Memory Clock, and 20+ Power Limit (Auto-Fan). After playing GTA 5 at very high settings (75 FPS average) for over an hour, the maximum temperature stayed at 68°C. Saints Row 4 was run in Ultra mode (70-90 FPS) for another hour, reaching a peak of 70°C. It hasn't crashed and doesn’t hit 80°C, which seems safe. This is definitely a solid overclock. 😉
For my configuration, I’m using:
- Intel® Core™ i7-6700 CPU @ 3.40GHz
- Radeon R9 270X Sapphire Dual-X 2GB OC
- Kingston DDR3L ValueRam 16 GB 1600 MHz (better RAM would be nice, but Skylake CPUs don’t officially support DDR3)
- Gigabyte Z170-HD3 DDR3 Motherboard
- Gigabyte SSD HyperX Savage 240 GB
- Old WD 650 GB Hard Drive (planning to upgrade to 2 TB 7200 RPM soon)
- HKC USP 5565550W Power Supply (not the top choice, but functional)
- Aerocool Strike-X ONE Advance case with one LED fan front and one non-led fan back – great airflow and room for more fans up to 12
I also added four Arctic Cooling Arctic F12 120 Fans and one NZXT LED ventilator (FZ 120mm RED).
When running Assetto Corsa at high frame rates, the temperature rises quickly. You're looking for safe fan speed adjustments without changing memory or clock speeds. Consider what default fan settings are recommended for optimal cooling under these conditions.
